Four electrons and two protons put at the edge of an isolated disk as shown moves in a clockwise direction at rate 1000 Rev. Per second calculate the current intensity produced by their motion and it's direction.

Four electrons and two protons put at the edge of an isolated disk as shown moves in a clockwise direction at rate 1000 Rev. Per second calculate the current intensity produced by their motion and it's direction if the electrons replaced by protons.

A slide in form of cuboid of dimensions of 12 cm, 6 cm & 2 cm if the current is connected with each opposite faces (1), (2) & (3).

So the ratio of their resistances is...

Two conductors of same material connected as shown, if the larger resistance is 40 Ω

Calculate the total current intensity in the circuit.

In the circuit shown the reading of the voltmeter is 4 V, so the reading of the current intensity passing through 6 is..

In the circuit shown the reading of the ammeter is 0.4 A so the value of X & Y are....

A straight wire of resistance 48 Ω . Form in a shape of closed loop, then connected to a battery as shown.

So the totat resistance between A & B is...

The equivalent resistance of three resistors is 2 Ω when they connected in parallel,

So the equivalent resistance when they connected in series is.....

In the circuit shown the ratio between the two readings of A1 & A2 is...
