| **What work has the electric current done in the fan motor if the voltage of the lighting network is 220 V, and the displaced charge is 10 C?**

Answer: 2200 J.

Solution to the problem: to solve this problem, you must use the formula: A = U * q, where A is the work of the electric current to move the charge in J, U is the voltage in V, q is the displaced charge. Substitute the known numerical values and get: A = U * q = 220 * 10 = 2200 J.
