Magnetism and electromagnetismQuestion 1082 of 1506

According to Faraday’s relationship, what sets the instantaneous voltage across a coil?

  1. The number of turns times the flux value
  2. The current times the flux
  3. The resistance of the coil times the flux
  4. Turns times rate of change of flux
Show answer

Correct answer: Turns times rate of change of flux

e = N × dΦ/dt.
