Passive Components RESISTORS To oppose the flow of electrons ( current). The symbols are shown below. Resistance is measured in units called “Ohm”. 1000 ohms is shown as 1k ohm (103 ohm) and 1000 k ohm is shown as M.ohms (106ohm). Resistors can be broadly of two types. • Fixed Resistors and Variable Resistors. Fixed […]

Introduction Electronic component can be divided into 2 types: Active and Passive components Resistors and Capacitors etc. are known as passive components because they can only attenuate the electrical voltage and signals and cannot amplify. Devices like transistors and operational amplifier(op Amps)can amplify or increase the amplitude and energy associated with the signals and so are […]
