มุมมอง 2.2K4 ปีที่แล้ว
This video introduces a basic concept of voltage division in a voltage divider circuits using a basic voltage divider circuit. Practically, the input voltage to the circuit is provided by a power supply such as a battery or electrical power supply and the output voltage is to be taken through the load resistor which is the device to be operated. The explanation is done by Mr. Pubudu Weerakoon (...

Derivation for the equivalent resistance of a parallel combination of two resistors
มุมมอง 1804 ปีที่แล้ว
This video explains the derivation for the equivalent resistance of a parallel combination of two resistors. Of a parallel combination, the voltage across each resistor in the combination is constant and the sum of the currents through each resistor of the combination is equal to the current sent to the combination from the external source. The lesson is explained by Mr. Pubudu Weerakoon (M.Sc....
Equivalent resistance of two resistors in series combination derived.
มุมมอง 2984 ปีที่แล้ว
This video shows the basic derivation for the equivalent resistance of two resistors in series combination. Conceptually, for a series combination, the current through each resistor is equal and the voltage across each resistor is additive. The lesson is explain by Mr. Pubudu Weerakoon (B.SC. , M.Sc.). For any question, you can refer to me. Thanking you.
Physics behind death-well circular motion problem solved.
มุมมอง 4374 ปีที่แล้ว
As a stunt rider performs his riding inside a death-well safely in a steady horizontal circle, the rider gets equilibrium vertically and accelerated horizontally towards the center of his circular path. Based on these conditions, the physics concepts are used to determine the range of speed that the rider has to be in bound in order to make the turns safely. The explanation is done by Mr. Pubud...
A car negotiating a bend of a level track explained.
มุมมอง 2634 ปีที่แล้ว
This explains the physics behind a situation of a car negotiating a bend of a level track. Since the track is level, the total frictional force acting on the car is horizontal thereby providing a necessary centripetal force to keep the path circular. Thank you. Pubudu Weerakoon.
Standing Waves on a Rope Explained.
มุมมอง 3344 ปีที่แล้ว
This video demonstrates how a standing wave is generated through simulation. The condition for the creation of standing waves is the existence of two homogeneous waves of the same frequency, wavelength, and amplitude traveling in the opposite directions in a same medium. The demonstration is explained by Mr. Pubudu Weerakoon.
