A sinusoidal ac voltage source in a circuit produces a maximum voltage of 11.8 V

Question

A sinusoidal ac voltage source in a circuit produces a maximum voltage of 11.8 V and an rms current of 7.35 mA . Part A Find the voltage amplitude. Part B Find the current amplitude. Part C Find the rms voltage of this source A sinusoidal ac voltage source in a circuit produces a maximum voltage of 11.8 V and an rms current of 7.35 mA . Part A Find the voltage amplitude. Part B Find the current amplitude. Part A Find the voltage amplitude. Part B Find the current amplitude. Part C Find the rms voltage of this source Part C Find the rms voltage of this source

Explanation / Answer

a) voltage amplitude = 11.8V

b) current amplitude = 7.35*sqrt(2) *10^-3 A = 10.39mA

c) RMS voltage = 11.8/sqrt(2) = 8.34V
