Answer:

Explanation:

The resistance offered is 2.5 ohms.

Given data:

Work done: 100 J

Charge Q = 20 C

Current I = 2 A.

Finding potential difference V from the relation of work done on a particular charge.

V=W/Q

So,

V=

V=  5 Volts

The potential in the circuit is 5 Volts.

According to Ohms law, the potential in a circuit (in volts) is equal to the product of current and resistance in the circuit.

V=  IR

Resistance R=

R=2.5 ohm.  

Therefore the resistance needed for the circuit to have potential of 5 volts is 2.5 ohm.

HOPE IT HELPS......
