Question

A sine wave has a positive zero crossing at 0 degrees and an 1M s value of 20 V. 3A. What is the peak value?22?. 5 38. What is the peak voltage at 180 degrees? 3C. What is the peak voltage at 270 degrees? 4. A sinusoidal 10Vp signal is applied to a single resistor of 1. 10 Ohms. 4A. What is the value of Irms? 4B. What is the value of Ipeak?

Answer 1

Step-by-step explanation:

The RMS value of the sinusoidal wave = 20V.

It's peak value or the amplitude = Vmax= 20×√2 Volts.

Peak voltage at 180° or π radians = 0 volt.

peak voltage at 270 degrees = -20√2 volt.

peak voltage of the sinusoidal wave = 10V.

RMS voltage = 10/√2 = 5√2 volts.

RMS current through 10 ohm resistor= 5√2/10 = 1/√2 Amp.

I_peak = 10v/10ohm = 1amp.
