WebResistors: Resistors are ubiquitous in electronics and arguably the first "real" electronic component we will be dealing with. ... So, if you had a 100K resistor and measured with a multimeter, it could read anywhere from 95K to 105K. For all of the circuits we will be building here, such approximate values will do fine. WebResistors serve to restrict electrical current flow in a circuit by creating resistance, which is measured in ohms. The equation for resistance reads R (for resistance) = V (for voltage) / I (for current measured in amps). A capacitor is an electromechanical two-terminal component that stores potential energy.
