The effective value of the voltage applied to the circuit v = 220V, the total resistance of the circuit is 10 ohm, to determine the amplitude of the current in the circuit.
In the circuit, the amplitude of the current will be equal to the amplitude of the voltage divided by the total resistance of the circuit, since the fluctuations in the current in phase coincide with the fluctuations in the voltage in the circuit.
Hence:
Im = Um / Z, Im is the amplitude of the current strength (A), Um is the voltage applied to the circuit (Um = 220 V), Z is the total resistance of the circuit (Z = 10 Ohm).
Then:
Im = Um / Z = 220/10 = 22 A.
Answer. The amplitude of the current in the circuit is 22 A.
