Principle In the last experiment, the students learned that self-induced
voltage is formed in a coil when a direct current circuit
is closed, and that this self-induced voltage counteracts the
connected voltage. Now, they should learn that self-induced voltage
formed when a circuit is opened has the same direction as the
original (i.e. connected) voltage. Benefits
Tasks What effect does a coil have when the circuit is opened? Investigate the direction of the self-induced voltage produced when a direct current circuit is opened.
