An ideal step-down transformer has a primary coil of 400 turns and a secondary coil of 25 turns. Its primary coil is plugged into an outlet with 110 V(AC), from which it draws an rms current of 0.83 A. 1.)What is the voltage in the secondary coil? 2.)Calculate the rms current in the secondary coil. 3.)Assuming that the transformer secondary is driving a resistive load, calculate the average power dissipated in the resistor.
A transformer is constructed with 533 turns in the primary coil and 10 turns in the secondary. If the rms voltage applied to the primary is 111 V, and the secondary is attached to a load with resistance 17 Ω, what is the rms current in the secondary? Express your answer in amps.
