    A COIL HAS AN INDUCTANCE OF 0.6 HENRY AND A RESISTANCE OF 2.5 OHMS.THE COIL IS IN SERIES WITH A CAPACITANCE OF 6.8 MICRO-FARADS ACROSS A 230V, 50 HZ, SINGLE PHASE SUPPLY. CALCUALTE THE CURRENT AND THE ANGLE OF PHASE DIFFERENCE BETWEEN IT AND THE APPLIED VOLTAGE. IF THE VOLTAGE HAS A 10 PERCENT HARMONIC(ie: AMPLITUDE OF HARMONIC IS 10 PERCENT OF THAT OF THE FUNDAMENTAL) OF 5 TIMES THE FUNDAMENTAL FREQUENCY, CALCUALATE THE CURRENT DUE TO THIS HARMONIC AND THE TOTAL PD ON THE CAPACITANCE.

    Accepted etiquette dictates "shouting" is indicated when one types in all capital letters. You didn't mean to shout, did you?:eek:

    Also, our forum guidelines call for knowing what you've done so far to solve the problem.
