230v is dropped over the appliance yes, but special diodes called zener diodes regulate voltage for an appliance. Also computer chargers have that box thing before the plug, that's a transformer that changes the voltage to the desired one.
Some appliances use the voltage as the 230vac. Some contain built in power supply's that either step the voltage up or down through the use of a transformer and can convert the ac to DC using a bridge rectifier.
do you need to know about the neutral wire in more detail for gcse like why it has 0volts or how it has 0volts or do we just need to know it has a pd of 0
Sorry, i don't understand how the current is pushed around the neutral wire if there is a potential difference of 0V. I thought current needed a p.d to be pushed around. Thank you!
The live wire is always carrying a current (unlike the neutral or earth). So if the electrician touches the live wire, a current will flow through their body to the earth (literally the ground) and this could be fatal.
@@robertdavison8382 Basically Electricity is always finding an easy path to discharge or neutralise, so when someone touches a live wire, he completes a circuit to the ground so electrons can pass via him to the ground to neutralise.
Freesciencelessons This means that the appliance would not work at all and the current from the live wire is never able to touch the metal case of the appliance.. It is correct?
Really good video, thank you - but I'm a little confused. Why is it that the earth wire takes on this electric charge instead of the metal on the washing machine ? How is the charge redirected/how is the earth wire activated ? If anyone can explain this to me it'd be a huge help, thanks.
Electricity will always take the path of least resistance to the ground. If the metal case becomes live the electricity will flow along the earth wire to the ground rather than through the body of anyone who touches the case as the earth wire has a much lower resistance than the human body.
Fuses are usually rated at 3 or 13 amps. If there is a 3 amp fuse in the plug and the current exceeds 3 amps the fuse wire inside the fuse case will melt and break the circuit.
Hi there, I understand the fuse will melt if the case becomes live and the current has exceeded the fuse's limit, but what would happen if the case became live but the current wasn't higher than the fuse's limit ? Thank you so much for your videos, you absolute legend.

Thank you, sir, The video is truly helpful...
what is your favourite science, sir?
He said his favourite is Biology but he likes teaching chemistry the most
Exteremely helpful just went through all yout physics videos as i have my mocks tdy. Hope everything goes well
Is there any ring main circuit videos around? P.s. this is a great help for people like me who leave revising for the last 2 weeks.
Do we have to know more specifically about how fuses work or is what you spoke about in this video all we need? Great video 👍
Thanks for the comment. You just need to know what's in this video.
@@Freesciencelessons thanks!
ur videos our so helpful rn. thx dude
i love this man
Cheers and thanks for the comment.
if the live is 230V and the neutral is 0V, does that mean that all appliances use up the 230V ?
230v is dropped over the appliance yes, but special diodes called zener diodes regulate voltage for an appliance. Also computer chargers have that box thing before the plug, that's a transformer that changes the voltage to the desired one.
Some appliances use the voltage as the 230vac. Some contain built in power supply's that either step the voltage up or down through the use of a transformer and can convert the ac to DC using a bridge rectifier.
This is pretty epic xxx
When it says that the energy is transferred what is it transferred to?
when you say that the neutral wire has a p.d of 0v compared to the live wire, what exactly does that mean?
do you need to know about the neutral wire in more detail for gcse like why it has 0volts or how it has 0volts or do we just need to know it has a pd of 0
you just need to know that it has a potential difference of 0v as it completes the circuit
Like how,how tf do I understand this in 4 mins and I learn nothing for 60 minutes every other day💀
Sorry, i don't understand how the current is pushed around the neutral wire if there is a potential difference of 0V. I thought current needed a p.d to be pushed around. Thank you!
Megan Maple there is still some p.d in there. It is “around” 0 so still some. He said it’s 0 compared to the live wire.
It takes out the charge, it simply completes the circuit and carries out the current.
Wish my grandpa watched this video. RIP
What's the fuse g
this guy is a legend
This video is very helpful. I am just confused on how someone gets electrocuted. Only wondering as that was a question on my latest mock exam
I am doing the aqa spec. Question was what happens if the electrician touches the live wire? It was something about electricity getting to the ground
The live wire is always carrying a current (unlike the neutral or earth). So if the electrician touches the live wire, a current will flow through their body to the earth (literally the ground) and this could be fatal.
@@robertdavison8382 Basically Electricity is always finding an easy path to discharge or neutralise, so when someone touches a live wire, he completes a circuit to the ground so electrons can pass via him to the ground to neutralise.
Thanks 😊 I appreciate your service to humankind
why does there need to be a neutral wire, can't there be live wire all round?
Yes, but its not as safe
bro whats that accent fam
love the vids keep up the good work
the accent of a legend
i love his point
where do you talk about R1 PLUS R2 = total
when it asks u to do the resistance
thats common sense tho it aint really a formula
who gave this guy the dislikes????? y thou y????
Best intro song ever.
Why and what will happen if the earth wire and the live wire both are connected to the pin near to fuse?
Tomorrow I have an exam... Plz help!
If the earth and live wires are connected to the same pin then an enormous current would flow down the earth and the fuse would melt all the time.
Freesciencelessons
This means that the appliance would not work at all and the current from the live wire is never able to touch the metal case of the appliance.. It is correct?
Please reply?
Yes if I understand your question correctly.
What most likely would happen is the RCD in the fuseboard would trip and the fuse would melt.
I have PTSD from this damn music.
live wire can be up to 325V?
no that is the peak of the alternating current, +325V and -325V but this is equivalent to the 230V of direct current
No it varies from around 220vac to 240 vac
hi please can do a video on short circuts
Ay thanks got 100 percent on my electricity test
Really good video, thank you - but I'm a little confused.
Why is it that the earth wire takes on this electric charge instead of the metal on the washing machine ? How is the charge redirected/how is the earth wire activated ?
If anyone can explain this to me it'd be a huge help, thanks.
because the earth wire has a lower resistance, so the current redirects to the easier path
the earth terminal is connected to the metal casing so that the current goes through the earth wire instead of causing an electric shock.
Electricity will always take the path of least resistance to the ground. If the metal case becomes live the electricity will flow along the earth wire to the ground rather than through the body of anyone who touches the case as the earth wire has a much lower resistance than the human body.
THANK YOU!
thank u sooooooo much sir!
So, what does the fuse do? I don't fully understand its purpose.
Killerfusions Psn if the current gets to high it basically melts and stops the current from flowing
if the live wire becomes loose, the fuse becomes really hot and melts. This causes the current to shut off so no one can get electrocuted
The fuse melts and shuts off the current 3:52
It just melts and breaks the circuit
Fuses are usually rated at 3 or 13 amps. If there is a 3 amp fuse in the plug and the current exceeds 3 amps the fuse wire inside the fuse case will melt and break the circuit.
Hi there,
I understand the fuse will melt if the case becomes live and the current has exceeded the fuse's limit, but what would happen if the case became live but the current wasn't higher than the fuse's limit ?
Thank you so much for your videos, you absolute legend.
the current would continue to flow through the wires as the current is at an acceptable, safe amount
Thank you sir
pls make a video shorting them out heh
