(b) If the primary is connected across 120 V rms, what is the open-circuit voltage across the secondary? ( ) V (c) If the primary current is 0.3 A, what is the secondary current, assuming negligible magnetization current and no power loss? ( ) A
The resistance of the primary and secondary coils of a transformer are 71 and 12 Ohms, respectively. both coils are made from lengths of the same copper wire. The circular turns of each of the same diameter. Find the turns ratio N_s/N_p.
A step-down transformer has 525 turns in its secondary and 12 500 turns in its primary. If the potential difference across the primary is 3510 V, what is the potential difference across the secondary?
The primary coil of a transformer contains 50 turns.. The primary coil is connected to an alternative voltage of 5.0 volts. The voltage across the secondary coil is measured 0.5 volts? How may turns does the secondary contain? If the primary current is 2.0 mA (mili-amperes,) what is the secondary current? 1 mA = 10-3 A
1. Is there direct contact between the primary and secondary coils in a transformer? 2. Why does the coil in a DC motor turn? Compare that to the means by which a generator produces current 3. Why are only a few types of atoms (iron, for example) magnetic?
