Grade 11Electromagnetic Induction

1) AN alternating voltage e=100sin314t is applied to a device which offers an ohmic resistance of 50 ohms in one direction while entirely preventing flow of current in opposite direction.Calculate: a) average and rms value of cuerrent? b) form factor? 2) An AC was measured as 7mA.Assume the alternating current to be sinusoidal.Calculate: rms,maximum value of current. 3) A voltage is given by v=50 + 30sinx (x=wt; x is = omega * t)in volts. Find the rms value of wave. i would like to see the detailed steps for solving the problems.... kindly help

1)average=2*(1/pi),rms=2/(2*sqrt(2)),form factor=rms/average

2)

2)rms=7*(pi)/sqrt(2),maximum=7*(pi)

3)rms=sqrt(2500+(900/2))=sqrt(2950)
