Answer 1

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

Make a rough sketch of the circuit using the material given with proper connection, then solve it.

Answer 2

Answer:

Thus, resistance of parallel combination is equal to resistance of resistors in series. So, potential difference across 20 resistance will be same as potential difference across the

other two resistors which are connected in parallel.
