A battery is a very quick negative voltage source. In a 9V battery, there are two terminals: anode for positive voltage and cathode for negative voltage. As most devices are designed for positive voltage supply, the negative terminal serves as a ground. Here when the negative terminal is used as ground, electrons are not returning.
For radios that use a standard 3-pin power cord, you can buy inexpensive 3-pin-to-cigarette adapter power cords that will work with the radio right out of the box. For cheaper CB radios that don''t use a removable 3-pin power cord, you''ll need to have a cigarette adapter that can be used with bare-end wires. Wire Directly to the Battery

Selecting the Appropriate Power Wire Gauge. The power wire gauge is a crucial factor in determining the capacity of your amplifier''s power supply. For most amplifiers, a 4-gauge or 8-gauge power wire is sufficient. However, for high-powered amplifiers (over 1000 watts), a 0-gauge or 1/0-gauge wire may be necessary.
The laboratory power supply shown in Figure 1-15 is a two channel power supply. Two channel power supplies have two outputs and each output can be set independently. A two channel power supply is more expensive than a single output power supply. The output current of the laboratory power is adjustable and can be limited by the user.
