The Voltmeter is placed in parallel between the positive and negative terminals of the battery.

The positive holes in the P-type silicon get attracted to the negative terminal of the battery.

The first is the positive terminal and the second is the negative terminal.

The negative terminal is called the cathode and the positive is the anode.

Category 3: Cylindrical cells with flat positive and negative terminals.

Category 4: Cylindrical cells with a protruding flat negative terminal.

If I have a wire that is 1 light year long from the positive to the negative terminals on a battery.

A bar across the side of the capacitor is usually used to indicate the negative terminal.

Attach the other exposed end of the wire to the negative terminal of the battery.

The can is the positive and the top the negative terminal.
