three type of electric device A, B, and C are connected in series across a 115 volt AC source, and the voltage drops across the individual units are equal. if EB leads EA by 90 elec deg and EC lags behind EA by 90 elec deg, what are the emfs across A, B, and C?

A voltage sources an IR drop across a 20 ohms R1, 60 volts across a 30 ohms R2, and 180 volts across a 90 ohms R3, all in series. How much is the applied voltage?

Please help me solve questions 1-5 using the given values found.

Q1) What is current in terms of charge? a) Current is measured 2A in a DC circuit * How much charge is involved in the process? * How many electrons are involved in the process? * The voltage source of this current is 12 Volts. What is the power produced by the source?
