An active resistance of 10 ohms is included in an alternating current circuit with a frequency of 50 Hz. What is the amplitude of current fluctuations at the amplitude of voltage fluctuations at the terminals of the active resistance of 50 V?
To find the magnitude of the amplitude of the current oscillations in the specified circuit, we apply the formula: Im = Um / Ra.
Variables: Um – amplitude of voltage fluctuations in the specified circuit (Um = 50 V); Ra – active resistance (Ra = 10 Ohm).
Calculation: Im = Um / Ra = 50/10 = 5 A.
Answer: A. The amplitude of current fluctuations in the specified circuit is 5 A.
