To calculate the current (I) and power (P) in the circuit, we can use Ohm's Law and the formula for power.

Given:
Resistance (R) = 4 ohms
Time (t) = 2 hours

First, let's find the current (I) using Ohm's Law:
Ohm's Law: V = I * R
Since the voltage (V) is not given, we cannot directly calculate the current using Ohm's Law.

Next, let's calculate the power (P) using the formula for power:
Power (P) = V * I
Since we do not have the voltage, we cannot directly calculate the power.

Therefore, without the voltage (V) being provided, we cannot accurately calculate the current (I) and power (P) in the circuit.
