# Impedance Calculation

*The red curve in the graph is the source voltage signal,
the green is the resistor voltage signal. Press the left mouse button on the graph to
display the values.*

#### Exercises:

Determine the rms current in the 1000 Ohm resistor of the
ac circuit.

The ac source has an rms voltage of 10V and a frequency of 1kHz.

Is the current inductive or capacitive?
