#### Explanation:

We'll have to use a few formulas here. First, we will calculate the current of the circuit using the charge. Then, we will calculate the voltage using the power and current. The final calculation will involve using Ohm's Law to find resistance.

Current calculation:

Current,

Voltage calculation:

Power is given by the formula

Resistance calculation:

Finally, we can use Ohm's Law to find the resistance,

Thus the resistance is 2
