Electrical principles

4. Electrical pressure, also called voltage.
7. The force that moves electrons.
10. A device that measures the force with which electrons are flowing.
11. A device that measures current flowing through a circuit.
12. The power expended when one ampere of direct current flow through a resistance of 1 Ohm.
13. Light __________ is the amount of light given off by a source such as a light bulb.
14. Kirchoff's ____________ states that current into a node must be equal to the amount of current out of a node
15. The opposite to current flow.

1. The rate at which energy is delivered to something. Measured in watts.
2. Kirchoff's ___________ states that the sum of the voltages in any closed loop must be equal to zero.
3. A device that consumes energy or power.
5. An electric current that flows in only one direction.
6. A circuit that has two or more branches for separate currents from one voltage source.
8. A device that measures current, voltage and resistance.
9. Current that reverses direction at a regular rate. Abbreviated as AC.
