The amplitude values of the voltage and alternating current in the resistor are, respectively, 24 V and 0.12 A. Find the effective values of the current and voltage.

We calculate the effective values of voltage and current in the indicated resistor using the formulas: U = Um / √2 and I = Im / √2.

Variables: Um – amplitude voltage (Um = 24 V); Im – peak current (Im = 0.12 A).

Calculation: 1) Effective voltage: U = Um / √2 = 24 / √2 = 16.97 V.

2) RMS current: I = Im / √2 = 0.12 / √2 = 0.085 A.

Answer: The effective voltage and current in the specified resistor are respectively equal to 16.97 V and 0.085 A.
