 Electric circuit Circuit symbols Circuit diagrams Diode Diode as forward biased and reversed biased Diode as a rectifier Diode as half wave rectifier Diod as full wave rectifier Transistors Series circuits Parallel circuits Effective or equivalent resistance in series circuits Effectice or equivalent resistance in parallel circuits Advantages of connecting lamps in parallel in lighting circuits Potential divider or Potentiometer Thermistors Light dependent resistor - (L.D.R.) Input transducers Capacitors Capacitance of the capacitor One Farad Different types of capacitors Time delay circuits Relay Rectifier circuits Transistor as switch Light sensitive switch Temperature operated alarms

The capacitance of the capacitor is said to be one farad, if a charge of one coulomb on a capacitor results in a potential difference of 1 volt accross it.
