A coil of wire when connected to a DC supply of 100 V takes a current of 10 A. When connected to an AC supply of 50 Hz, the current is 5 A. Explain the difference and calculate the inductance of the coil. showing full working out
Added by Lorena A.
Step 1
The difference in current between the DC and AC supply is due to the fact that the coil has inductance, which resists changes in current flow. In DC, the current is constant, so the inductance does not have much effect. In AC, the current is constantly changing Show more…
