Two resistors, A and B, are connected in parallel across of a 6V battery. The current through B is found to be 2.0 A. When the two resistors are connected in series to the 6V battery, a voltmeter connected across the resistor A measures a voltage of 4V. Find the resistances of A and B.

Resistance of A is and B is

Explanation:

The voltage across both the resistances will be the same as they are connected in parallel.

V = Voltage = 6 V

Resistance is given by

Series connection

The current is constant in series connection

The resistance of A is and B is .

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes
