37.5 - 37.6
Karten in diesem Stapel (7)
- 1What does a transformer actually transform—voltage, current, or energy?voltage & current, but not energy.
- 2What does a step-up transformer step up, voltage, current, or energy?voltage
- 3How does the relative number of turns on the primary and the secondary coil in a transformer affect whether is it a step-up or step-down transformer?If the secondary side has the most turns, it is stepping-up
- 4On a transformer, the number of secondary turns is 10 times more than the primary turns, and the input (primary) voltage is 6 volts. The voltage induced on the secondary coil is ______ volts.60
- 5In a transformer, how does the power input to the primary coil compare with the power output of the secondary coil?They should be the same.
- 6Why is the advantage to transmitting electric power long distances at high voltages?The high voltage has lower current, so there is less friction (more energy loss).
- 7I have a transformer where the secondary voltage is twice the primary voltage. How does the current in the secondary of a compare with the current in the primary? The current in the secondary is ______.half as much
