| **What is the work of an electric current if a current of 0.6 A flows through a light bulb connected to a 4.5 V current source for 15 s?**

Initial data: U (voltage at the current source) = 4.5 V; I (current in a light bulb) = 0.6 A; t (duration of the flow of electric current through the light bulb) = 15 s.

The work of the electric current can be determined by the formula: A = U * I * t.

Let’s perform the calculation: A = 4.5 * 0.6 * 15 = 40.5 J.

Answer: The work of the electric current was 40.5 J.
