Question

What is the resistance of a circuit with a current of 48 amps and a voltage of 12 volts?

a: 0.25 ohms
b: 60 ohms
c: 4 ohms
d: 576 ohms

Answer 1

a: 0.25 ohms

Step-by-step explanation:

The resistance of the circuit can be calculated by using Ohm's Law:

`V = IR\\\\R = (V)/(I)`

where,

R = Resistance of the circuit = ?

V = Voltage = 12 volts

I = Current = 48 A

Therefore,

`R = (12\ V)/(48\ A) \\\\R = 0.25\ ohms`

Hence, the correct option is:

a: 0.25 ohms
