## Question:

The current in a resistor is given by {eq}I = (7.2\ \rm{A}) \sin(60 \pi t) {/eq} when a voltage given by {eq}V = (240\ \rm{V}) \sin(60 \pi t) {/eq} is applied to it.

1. What is the resistance value?

2. What is the frequency of the voltage source?

3. What is the period of the voltage source?

## Resistance in Alternating Current:

When we connect a sinusoidal voltage to a resistor we can appreciate that the current which passes through it has the same shape, but perhaps a little more attenuated, since it does not produce any type of phase shift. Additionally, this element has a fixed resistance value that is not altered by the frequency.
