When a load is connected to a circuit, the voltage drop across the load compared to the no-load voltage will typically increase. This is due to the following factors: 1. Internal Resistance: * All components in a circuit, including the power source, have some internal resistance. * When no load is connected, there's no current flowing, so there's no voltage drop across this internal resistance. * When a load is connected, current flows through the circuit, including through the internal resistance. * According to Ohm's Law (V = IR), this current flow causes a voltage drop across the internal resistance, reducing the voltage available at the load terminals. 2. Wire Resistance: * The wires used to connect components in a circuit also have resistance. * Similar to internal resistance, this wire resistance causes a voltage drop when current flows through it. * This voltage drop further reduces the voltage available at the load. 3. Load Impedance: * The load itself has impedance (a combination of resistance and reactance). * A higher load impedance will result in a larger voltage drop across the load. In summary: * No Load: The voltage at the load terminals is equal to the source voltage. * With Load: The voltage at the load terminals is lower than the source voltage due to voltage drops across internal resistances, wire resistances, and the load impedance itself. The magnitude of the voltage drop depends on several factors, including: * The internal resistance of the power source * The resistance of the wires * The impedance of the load * The amount of current
Sir, can you help me about Dc to Dc step down buck converter out put voltage are not getting. (300watt 10 amp buck converter). Which parts are replace?
Sir, you have to check the IC and power Schottky rectifier of the converter so that it is not bad, if bad then replace it and also check the capacitor of the converter properly, no capacitor is bad.
Saludos desde Venezuela excelente video muy buena su explicación
Nice ❤

Sir apne ye sb sikhne k liye konsi study ki hee muje bi sikhna hee
ITI Electrician and Polytechnic Electrical &Electronic.
How many ampere sir?
15 ampere
Sir if i put the transistor on heat sink do i need to use mica insulator for 2n3055?
@@technical7771 nemože biti 15A jer 2n3055 ne drži 15 A makar bila i 2 u seriji. (vidi koliko A izdrži 1 uz jako dobar hladnjak)
The soldering is very bad!
Sir, thank you very much for giving us your feedback.
