- Charging
- Batteries have chemicals to produce energy
- Smoothing capacitor-supplies current to the output
- Changes near the peak value of the varying DC
- Positive terminal connected to n-type- no current passes, gap widens
- Vice versa for p-type semi conductor
- The space either side of the junction has no electrons or holes
- N-type and p-type semi conductor
- Excess of electrons (n-type)
- Shortage of electrons (holes) (p-type)
- An AC supply to a single diode produces a half wave rectified output
- A resistor always used to protect the diode in series
- Four diodes-bridge circuit
- Capacitor-makes the output smoother
- Capacitor connected to the DC power supply becomes charged
- Stores electrical energy connected to a resistor
- Voltage decreases and capacitor discharges
- Voltage increases until it is equal with the supply voltage
- Stores electrical energy connected to a resistor
