@ ajith electric current can be defined as the flow of electrons , " for examples – suppose u take a electric wire , then inside that there will be a lot of free electron , and when u will connect it ...

After just closing the switch at time t=0, I1 = e/2R as the capacitor becomes short circuit. At time t= infinity, the capacitor behaves as an open circuit brach and therfore, I2 = e/3R Hence, I1/I2=...
Becaue Resitance alwayas resist and hence would block the current or charge and dissipates in the form of heat or light. From joule’s law of Heating, H = i^2Rt And capacitance has the capacity to...
@ ajeeth they are diffrent configurations that are required to operate the electric circuit properly , in series u have overall resi more than the single and in parallel u have overall resi less than ...
Above question is missing Pls post again
Question statement is missing Pls post again
Hi I believe your image is not uploaded properly.
Electric current is the rate of charge flow past a given point in an electric circuit, measured in Coulombs/second which is named Amperes. In most DC electric circuits, it can be assumed that the...
@ tammana fuse wire have a very low melting point , when a high current flows through the circuit due to overloading or short circuit , the wire gets heated or melts . and the no of turns in the...
t = 20 = L/R and after adding a resistance of 2 ohm, t’ = L/(R + 2) = 2 dividing t/t’ we get, (R+2)/R = 20/2 = 10 R = ¼ ohm and L = 5 H
Dear Shrish, U need to menion hefre the combination of resitances first how they are connected or plz attach an image clearly. Without that it would be impossible to solve. Thnx!
HI IRFAN, every thing is ok! but what is the question??:P plz ask the question again. we will surely help you :)
HI EKTA , I THINK THE QUESTION IS NOT CLEAR, what do uh mean by the emf of the combination? plz give any figure (if any) that will make the question more clear :)
@ ajay the neutral is the return path for current in single wire districution system and connected to the ground , this is called as single wire earth return . the neutral allow unused current to...
HI, ANSWER IS NOT D!! THE CURRENT SHOULD FLOW THROUGH THE BULB, IT SHOULD NOT BE SHORTED! S 3 SHOULD ALWAYS BE OPEN! AND EITHER S 1 OR S 2 SHOULD BE CLOSED (OR BOTH SHOULD BE S1 AND S2 SHOULD BE...

Power delivered to the load resistance, To find the maximum power , differentiate the expression with respect to resistance R L and equate it to zero. Thus, Thus in this case, the maximum power will...
@ krupal what happens is when current are flowing in a wire , then these free electrons will going to constitute the current in the wire , and these cannot be decrease or increase , these number will ...
Current and voltage are vector product in a.c. only in wave from . In d.c. current is scaler product because it has only one sign and can not get resolved it.
