1 Ohm's Law

Ohm's Law

 

Digital meters measure the current and the voltage in a simple circuit of a battery and resistor. The rheostat is adjusted so that the meters read the same, differing only by a factor of 1000. The battery pack contains six 1.5 volt batteries in series. Change the number of batteries in the circuit OR change the resistance and observe that the meters change proportionally.

4 Capacitor and Light Bulb

RC Circuits

A 5600 microfarad capacitor, a light bulb, and a 120 V dc supply in series show a long time constant where the bulb dims as the capacitor charges.
