- 1Power Supply WattagePower supply expressed in watts (W).
- 2Voltage(V)Measured in
Volts (V)
Description
A measure of work requires to move charge from one location to another .
A computer power supply produces several different voltages.
' - 3Current(I)Amperes or Amps(A)
Description
Measure the amount of electrons moving through a circuit per second.
Computer power supplies deliver different amperages for each output voltage. - 4Resistance(R)Measured in
Ohms(O)
Description
Refers to the opposition to the flow of current in a circuit.
Lower resistance allows more current to flow through a circuit.
A good fuse has low resisitance - 5Power(P)Measured in
Watts(W)
Description
measure the work required to move electrons through a circuit per second (current).
Computer power supplies are rated in watts. - 6Ohm's LawResistance: V = IR
Current:P = VI - 7NoteA power supply with a higher wattage rating has more capacity; therefore, it can handle more devices.
- 8NoteBack of power supplies is a small switch called the voltage selector switch.
A power supply with this switch is called a dual voltage power supply.
Setting the voltage switch to the incorrect input voltage could damage the power supply and other parts of your computer.
If a power supply does not have this switch, it automatically detects and sets the correct voltage. - 9NoteDo not open a power supply. Electronic capacitors located inside of a power supply, can hold a charge for extended periods of time.
