A sine wave generator has an output waveform v(t) = 14.14 cos ( 2 PI 1000 t).
A 100 W resistor is connected to the generator.
a. What is the frequency of the waveform in Hz?
b. What is the rms (root mean square) voltage across the resistor?
c. What is the rms current through the resistor?
d. How much power is dissipated in the resistor?
