Voltage Current and Resistance

This electronics video tutorial provides a basic introduction into voltage, current, and resistance. The unit of voltage is the volt which is a measure of electric potential energy per unit of charge. Current is measured in amps and 1 amp is equal to the flow of 1 coulomb of charge per second. Resistance is provided by device elements known as resistors. Resistance is measured in ohms. This video discusses how to calculate the voltage of a battery, the internal resistance of a hair dryer, and the current flowing in a circuit using ohm's law. It discusses the direction of conventional current vs electron flow.
