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.
