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

In a network as shown in the figure the potential difference across the resistance 2R is (the cell has an emf of E and has no internal resistance):

In an A.C. series circuit of L-R voltage applied is 220 V, if the potential difference across two ends on inductor is 176 V then the potential difference across two ends of the resistance will be ……

A resistor of 200 Omega and a capacitor of 15.0 muF are connected in series to a 220 V, 50 Hz ac source. (a) Calculate the current in the circuit, (b) Calculate the voltage (rms) across the resistor and the capacitor. Is the algebraic sum of these voltages more than the source voltage? If yes, resolve the paradox.
