PHY02 - CO3 REVIEWER

It is the maximum potential difference exist between the two terminal.

The battery creates an electric field within and parallel to the wire, directed from the positive toward the negative terminal.

• True

• False

Formula and SI Unit for Electric Current

he flow of charge inside a wire and crossing an imaginary surface that is perpendicular to the charge motion

• Electric Current

• Electromotive Force

• Conventional Current

• Current

Two kinds of current electricity:

• Direct Current (DC) – charges move around a circuit in the same direction at all times.

• Alternating Current (AC) – charges move in changing direction from moment to moment.

• Direct Current (DC) – charges move in changing direction from moment to moment.

• Alternating Current (AC) – charges move around a circuit in the same direction at all times.

• A hypothetical flow of positive charges that would have the same effect in the circuit as the movement of the negative charges that actually does occur.

• In a circuit, electrons actually flow through the _____

• • metal wires.

• • wires.

• • device.

• batteries.

It states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperatures remain constant.
