Lab 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.
