A closed electric circuit is set up so that there is a resistance of $8.4\Omega$ and a voltage of . What is the current in the circuit?

CORRECT

For this problem, use Ohm's law: .

We are given the voltage and the resistance. Using these terms, we can solve for the current.

$21.6V=I(8.4\Omega)$

$\frac{21.6V}{8.4\Omega}=I$
