Question

4. Use Ohm's Low to determine the resistance in a circuit if the voltage is 12.0 volts and the

current is 4.0 amps.
8.0 ohms
48 ohms
3.0 chms
12 onms​

Answer 1

`3.0 \Omega`

Step-by-step explanation:

Ohm's law states that the potential difference across a resistance is proportional to the current flowing through it, according to the equation:

`V=RI`

where

V is the potential difference

R is the resistance

I is the current

In this circuit,

V = 12.0 V

I = 4.0 A

Solving for R, we find the resistance:

`R=(V)/(I)=(12.0)/(4.0)=3.0 \Omega`
