A $\small 12V$ battery supplies power to a circuit with a current of $\small 16A$ . What is the resistance in this circuit?

$0.75\Omega$

CORRECT

$1.33\Omega$

$9\Omega$

$192\Omega$

$12\Omega$

To find resistance from voltage and current, we will need to use Ohm's law:

$R= \frac{V}{I}$

We are given the voltage and current, allowing us to solve for the resistance.

$R = \frac{12V}{16A} = 0.75\Omega$
