How will you conclude that the same potential difference (voltage) exists across three resistors connected in a parallel arrangement to a battery ?

How will you conclude that the same potential difference voltage exists across three resistors connected in a parallel arrangements to a battery?

A 2.0 mu F capacitor and a 4.0 mu F , capacitor are connected in parallel across in 300V potential difference (a) What is the total energy stored by them? (b) They are next connected in series across that potential difference. What is the ratio of the total energy stored by them in the parallel arrangement to that in the series arrangement?

A battery of internal resistance 3Omega is connected to 20Omega resistor and the potential difference across the resistor is 10V. If another resistor 30Omega is connected in series with the first resistor and battery is again connectecl to the combination, then calculate the e.m.f and terminal potential difference across the combination..

In series circuit, potential difference across each resistor is always the same.

Draw a circuit diagram of an electric circuit containing a cell, a key, an ammeter, a resistor of 2Omega in series with a combination of two resistors [ 4Omega each] in parallel and a voltmeter across the parallel combination. Will the potential difference across the 2Omega resistor be the same as that across the parallel combination of 4Omega resistors? Give reason.

An inductor is connected in series with a resistor of resistance 1000 Omega and a capacitor of capacitance 2 mu F. Potential difference of 100 V exists across the resistor . Angular frequency of source is 200 rad/s, and the same is equal to resonant frequency of the circuit find the rms voltage across inductor .
