|
circuit |
A circuit is an unbroken loop of conductive material that allows electrons to flow through continuously without beginning or end. |
|
|
voltage |
Voltage is the measure of specific potential energy between two locations. Voltage is the potential energy stored in the form of an electric charge imbalance and capable of provoking electrons to flow through a conductor. Symbol: V or E Unit: Volt, V |
|
|
current |
Current is a uniform flow of electrons through a circuit. Symbol: I Unit: Amperes, A |
|
|
closed circuit closed switch |
A closed circuit is an electric circuit through which current can flow in an uninterrupted path. A closed switch is an electric switch through which current can flow in an uninterrupted path. |
|
|
open circuit open switch |
An open circuit is one where the continuity has been broken by an interruption in the path for electrons to flow. An open switch is one without continuity: electrons cannot flow through it. |
|
|
resistance |
Resistance is the measure of opposition to electric current. Symbol: R Unit: Omh, Ω |
|
|
Omh's Law |
V = I * R Voltage = Current * Resistance |
|
What is the amount of current (I) in this circuit? |
|
|
What is the amount of resistance (R) offered by the lamp? |
|
|
What is the amount of voltage provided by the battery? |
|
|
|
Power |
Power is the measure of how much work can be done in a given amount of time. Symbol: P Unit: Watts P = I*E Watts = Current * Voltage |
