1 Xc = waC V = IX XR = R X = waL First consider an AC voltage source with a driving frequency wa and a purely resistive load. 1) Resistive Load I Suppose the driving frequency wa increases. What happens to the voltage amplitude VR? Choose one of the following. Increases Decreases Stays the Same 2) Resistive Load II Suppose the driving frequency wa increases. What happens to the current amplitude IR? Choose one of the following.

1. Build the following circuit. Use the function generator to obtain the specified AC input voltage. D4 D1 + RL 1.2K< + Vs(N D3 Y D2 9V sin(2n 50 t) Verify the amplitude and frequency of the output waveform on the load resistor, RĻ. Peak voltage: Waveform period: Frequency 1.b) Vs frequency is 50 Hz. Why the V frequency is 100 Hz?

Add the two voltages below together (phasor voltages are RMS). ?ଵ =60 ? ∠ 0° ?ଶ =80 ?∠ 270° a) What is the resultant as a phasor using RMS voltage and degrees? b) What is the resultant voltage as a sinusoidal equation if the frequency is 100 Hz?
