This course serves to instruct sound recording technology through the concepts of voltage, current, power, resistance and Ohm's law; series, parallel and resonant circuits, Kirchhoff's voltage and ...

The symbol for resistance is R, it is measured in ohms \((\Omega )\). The symbol for current is I, it is measured in amperes \((A)\).

If you increase the number of lamps in a series circuit, there will be less current. The lamps resist the current, so if you put more lamps into the circuit, there is more resistance. Figure ...
