DC and AC resistance of a coil I (observation experiment)

DC and AC resistance of a coil I (observation experiment)

LP3.4.6.1

To carry out all experiments from this subject area, we offer you a complete set: CLICK HERE

Description

In this experiment, the students will examine the resistance of a coil in a DC circuit and in an AC circuit by using the lighting up of a bulb as an indicator of resistance. They realise that a coil in an AC circuit has a greater electrical resistance than in a DC circuit.
