Answer : The resistance in the circuit is, 2 ohm
Solution : Given,
Voltage = 1.5 V
Current in the circuit = 0.75 A
According to the Ohm's law, the current passing through the conductor is directly proportional to the voltage and is inversely proportional to the resistance.
Formula used :

where,
V = voltage
I = electric current
R = resistance
Now put all the given values in the above formula, we get


Therefore, the resistance in the circuit is, 2 ohm
