voltmeter
Its a power source such as a battery - Wire from the Positive on the battery to one contact on the lamp and a wire from the Negative of the battery to the other contact on the bulb
The battery or other power supply that energizes the circuit is.
Consider a battery for a moment. A battery can be a source or sink type of power source. A light bulb would be considered a source current. When a battery or other item is being charged is it considered a sinking source.
This can occur due to a light remaining on or some other electric device is using energy from the battery. The electrical system must be evaluated to determine the source of the parasitic draw. Typically however, if the source cannot be obtained, the battery is considered bad.
an electric circuit consists of a voltage source (like a battery), something to use up some of the voltage to keep it from short circuiting ( like a light bulb or a motor), and wires to connect the positive end of the battery to the light bulb or other device, then more wire to connect the other part of the bulb to the negative end of the battery.
what
The voltage source (such as a battery) is what provides the energy needed to push the electrons through the circuit. Electrons flow from the negative terminal (cathode) to the positive terminal (anode) of the voltage source in a closed circuit.
d. a battery Batteries use chemical reactions to release electrons at one terminal and accept them at the other terminal, generating electrical energy that can be used to power devices.
Unless you have some other source of information, your only option is to measure it - possibly using a protractor.
