**Hint**

Power absorbed by a resistive element:

$$$P=VI=\frac{V^{2}}{R}=I^2R$$$

where
$$V$$
is voltage,
$$I$$
is current, and
$$R$$
is resistance.

**Hint 2**

Based on the problem statement’s givens, solve for resistance using the equation:

$$$P=\frac{V^{2}}{R}$$$

Power absorbed by a resistive element:

$$$P=VI=\frac{V^{2}}{R}=I^2R$$$

where
$$V$$
is voltage,
$$I$$
is current, and
$$R$$
is resistance.

Solving for Resistance using the problem statement’s knowns:

$$$P=\frac{V^{2}}{R}=\frac{30^{2}}{R}=300$$$

$$$R=\frac{900}{300}=3\:\Omega $$$
