Principle The students know that self-induced voltage is generated in a
coil in a direct current circuit when the circuit is closed or
opened. They also know which direction the sel-finduced current
has. The second experiment is used to provide a semi-quantitative analysis of the dependency of inductive resistance on the number of turns and the coil core. Benefits
Tasks How does a coil act in an alternating current circuit? Prove that a coil in an alternating current circuit possesses a resistance in addition to the ohmic resistance from its wound wire and investigate the factors responsible for this additional resistance.
