The current passing through the ideal ammeter in the circuit given below is

In the Wheatstone\'s network given, P = 10 Ω, Q = 20 Ω, R = 15 Ω, S = 30 Ω. The current passing through the battery (of negligible internal resistance) is

A copper wire of resistance R is cut into ten parts of equal length. Two pieces each are joined in series and then five such combinations are joined in parallel. The new combination will have a resistance

In the circuit shown the value of I in ampere is

In the circuit shown, the point \'13\' is earthed. Thepotential at the point \'A\' is

In the circuit shown below, the cell has an e.m.f. of 10 V and internal resistance of 1 ohm. The other resistances are shown in the figure. The potential difference V_A– V_B is

A wire of resistance R is cut into \'n\' equal parts. These parts are then connected in parallel. The equivalentresistance of the combination will be

What is the current (i) in the circuit as shown in figure

n equal resistors are first connected in series and then connected in parallel. What is the ratio of the maximum to the minimum resistance?

A uniform wire of 16 Ω is made into the form of a square. Two opposite corners of the square are connected by a wire of resistance 16 Ω. The effective resistance between the other two opposite corners is
