Voltage, Current, and Resistance

Shedding Light on Electricity

In this episode, we look at how electrical equipment is designed to use the right amount of current for the voltage supply that it's designed for. After a brief recap on electric current, we look at what voltage is and how it is measured. we then look at the concept of resistance. At a simple level, some materials are conductors and some materials are insulators, but not all conductors conduct equally well. The amount of current that flows in a household appliance depends on the appliance's resistance
