To calculate the power of the electric current of the lamp, we apply the formula: Q = I ^ 2 * R.
The value of the variables: I – current strength (I = 0.6 A); R is the resistance of the lamp used (R = 5 ohms).
Let’s perform the calculation: Q = I ^ 2 * R = 0.6 ^ 2 * 5 = 1.8 W.
Answer: The power of the electric current in the lamp used is 1.8 watts.
