Representation of AC Current and Voltage by Rotating Vectors — Phasors

The RMS value of current in an ac circuit is $10 \mathrm{A}$. What is the peak current?

There are two circuits, one with pure inductive load and the other with pure capacitive load. What is the net power absorbed by each circuit over a complete cycle. Explain your answer.

A coil of inductance $0.50 \mathrm{H}$ and resistance $100 \mathrm{\Omega }$ is connected to a $240 \mathrm{V}, 50 \mathrm{Hz}$ ac supply. What is the time lag between the voltage maximum and the current maximum?

A coil of inductance $0.50 \mathrm{H}$ and resistance $100 \mathrm{\Omega }$ is connected to a $240 \mathrm{V}, 50 \mathrm{Hz}$ ac supply. What is the maximum current in the coil?
