The maximum current Io passing through a resistance R connected with an alternating voltage source Vo is given by:
Correct answer: B. Io=Vo/R
- A. Io=RxVo
- B. Io=Vo/R
- C. Io=R/Vo
- D. Io=Vo x R
Explanation
The correct option, "Io = Vo/R," follows Ohm's law for AC circuits, stating that the maximum current (Io) through a resistor (R) connected to an alternating voltage source (Vo) is equal to the voltage (Vo) divided by the resistance

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
