What electrical capacity should a capacitor have so that when it is included in the circuit. With a voltage of 220 V, get a charge of 2.2 * 10 ^ -3 cells.
Initial data: U (voltage at the ends of the circuit) = 220 V; q (value of the required charge) = 2.2 * 10 ^ -3 Cl.
The required electrical capacity of the capacitor can be calculated by the formula: C = q / U.
Let’s perform the calculation: C = 2.2 * 10 ^ -3 / 220 = 0.00001 F = 10 μF.
Answer: The capacitor must have an electrical capacity of 10 μF.
