Return to Resistance, EMF, and Current
Description:
A safety bulb is lit up when a conductive path connects the two leads. Works with upwards of 20 people. Brightness can vary with resistance and quality of contact to double as a good demonstration of resistance as well as conduction. You might also wet your hands and touch the leads to show a sudden decrease in resistance. Inserting a metal rod, a plastic rod, and a resistive material in the circuit can show differences between conductors and insulators. NOTE: Does not work if people in circuit are wearing gloves.
