Problem: a) What is the emf frequency f? b) What is the value of the resistance R? c) Draw the resistor's voltage and current phasors at t = 15 ms

Frequency:

$f = \frac{1}{T}$

From Ohm's law:

$i_{0} R = ε_{0}$

From the figure, the period, T = 0.04s

The period is the time taken for full oscillation.

a) What is the emf frequency f?

b) What is the value of the resistance R?

c) Draw the resistor's voltage and current phasors at t = 15 ms
