Chapter , Problem 80(choose chapter or problem)
Atransformer has in the primary and in the secondary. (a) Is this a step-up or a step-down transformer? (b) If the primary is connected to a 120-V-rms voltage source, what is the open-circuit rms voltage across the secondary? (c) If the primary rms current is what is the secondary rms current, assuming negligible magnetization current and no power loss?
