Figure 2.4 shows the input
voltage waveform of figure 2.3.
Figure 2.5 shows the input
voltage waveform is in phase with the current I of figure 2.3.

2.1 Part One
Set up the circuit (software).
In this circuit diagram,
note the following:
VP = 10 volts, f = 1K Hz, T = (1 / f) = (1 / 1K) = 1 ms.
The voltmeter displays the
RMS value of the voltage across the resistor R.
The ammeter displays the RMS
value of the current in the circuit.
IP = VP / R = 10 / 1K = 10 mA.
Irms = (0.707) (10m) = 7.071 mA.
VR (rms) = Irms R = (7.071m) (1K) = 7.071 V.
