  1. 1What does a transformer actually transform—voltage, current, or energy?voltage & current, but not energy.
  2. 2What does a step-up transformer step up, voltage, current, or energy?voltage
  3. 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
  4. 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
  5. 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.
  6. 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).
  7. 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
