A rms voltage of is required for a device whose impedance
Chapter , Problem 79(choose chapter or problem)
A rms voltage of is required for a device whose impedance is (a) What should the turns ratio of a transformer be, so that the device can be operated from a line? (b) Suppose the transformer is accidentally connected in reverse with the secondary winding across the line and the load across the primary. How much rms current will then be in the primary winding?
