Solve the problem.
-According to Ohm's law, the electric current $I$, in amperes, in a circuit varies directly as the voltage $\mathrm{V}$. When 20 volts are applied, the current is 3 amperes. What is the current when 10 volts are applied?
A) 66.6666667 amperes
B) 6.67 amperes
C) 33 amperes
D) 1.5 amperes

Ohm's law states $I = \frac{V}{R}$, where $I$ is current, $V$ is voltage, and $R$ is resistance. Given $I = 3$ amperes at $V = 20$ volts, when $V = 10$ volts (half of 20 volts), the current $I$ will be half of 3 amperes, which is 1.5 amperes.
