Complex numbers circuit theory

A voltage generator has an internal impedance of 3+j8 ohms. this generator is connected to a load impedance of 20+j15 ohms.if the voltage accross the load impedance is to be 80+j0 volts, calculate the value of generator EMF E. A capacitor is now connected across the load impedance. by calculating the current drawn from the so ...continues
