K7-03 INDUCTOR DELAYING A LAMP

ID Code: K7-03
Purpose: Demonstrates the timing of current in a switched inductor circuit
Description: An inductor and light bulb are connected across a battery with a switch. In parallel with this inductor and light bulb is a second identical light bulb. The separate light bulb will light immediately, but the light bulb in series with the inductor will be delayed in lighting until the current reaches a high enough level. The delay time is related to the L/R time constant of that leg of the circuit.
