# 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

###### FREE Expert Solution

Frequency:

$\overline{){\mathbf{f}}{\mathbf{=}}\frac{\mathbf{1}}{\mathbf{T}}}$

From Ohm's law:

$\overline{){{\mathbf{i}}}_{{\mathbf{0}}}{\mathbf{R}}{\mathbf{=}}{{\mathbit{\epsilon }}}_{{\mathbf{0}}}}$

a)

From the figure, the period, T = 0.04s

The period is the time taken for full oscillation.
