A resistor is a component of an electric circuit that resists the flow of current and protects delicate electronic equipment from surges. The resistor allows a specific amount of current to pass, but inhibits a high voltage spike that could cause...

A resistor is a two-terminal electrical or electronic component that opposes an electric current by producing a voltage drop between its terminals in accordance with Ohm's law: R = \frac {V}{I} The electrical resistance is equal...
