1. Electric Current
If we connect the lamp to a source of alternating current (ac), current will flow through the lamp in both directions (first one way and then the other).

2. Using An Appliance On Foreign Current
appliances are designed to be used on 110 to 120V ac, 60 Hz current. If an appliance is going to be used on the 220V ac, 60 Hz current found in many European and other foreign countries, the 110V appliance can be coupled to the 220V current through a 2:1 stepdown transformer.

3. Converting AC To DC
Many modern appliances, while operating on ac, use dc motors or rechargeable dc batteries that require the ac to be converted to dc at some point within the appliance.

4. AC Motors
Single-phase ac motors use only one phase of alternating current. A polyphase motor uses more than one phase of ac, and the difference between the phase is enough to start the motor and keep it running.

5. Universal Motors
So a universal motor is one which can be operated from either ac or dc with nearly the same output characteristics from the motor.

6. Solid - State Devices
You have already seen how one such device, a diode, is used to convert ac into dc. There are many other small electronic components which can be used in the control circuitry of appliances and tools.

7. Bench - Type Continuity Checker
With 110V ac applied to terminals 3 and 4 of the four-terminal barrier strip, 30V is induced into the isolated circuit as measured at test receptacle J and across terminals 1 and 2 of the terminal board.

8. Other Devices
6V, 16 mA LED (light-emitting diode), and a female ac receptacle. The plug at the end of the line cord of the aquarium heater is plugged into receptacle P.

9. Variable AC Power Supply
For this purpose, a variable ac power supply can serve the repairman well. This device features a metered knob for adjusting output to the voltage required (normally 0- 140V).

10. Multivoltage AC / DC Power Supply
The power supply can be used for bench operation of low-voltage ac and dc appliances and control devices. Transformer T may be a Stancor P-8364, which has three 12V secondaries of which one is centertapped.
