A resistor is an electronic component that is designed to offer a desired amount of resistance to the flow of current.
Resistors have impedance
the energy stored in a resistor is
and the power dissipated by a resistor is
where I is the current and V is the voltage.
The resistance of a resistor is indicated by a series of colored circular bands around it according to the encoding summarized below.
Battery, Capacitor, Inductor, Joule's Law, Resistance
