Energy made available by the flow of electric charge through a conductor.
The AMOUNT of electric current that can flow through an object.
The flow or speed of an electric charge through an object.
When opposite poles come together
When like poles push away from each other
A charge that occurs when an object has MORE electrons than protons
A charge that occurs when an object has FEWER electrons than protons.
A material that easily transfers an electrical charge, such as the copper wire.
A material that does NOT transfer an electrical charge, such as the plastic around these wires.
To move from one place to another.
another word for rubbing. It can slow the movement of electricity in a light bulb.
Something that is the source of an electric current, such as a battery.
Friction inside a light bulb that slows the movement of electricity.
The voltage is 21 V, and the current (I) is 7 A. Find the resistance.
The voltage in a radio is 120 V, and the current (I) that runs through it is 6 A. Find the resistance.
The resistance in a light bulb is 8 ohm. The voltage is 56 V. Find the current (I) running through the light bulb.
A kind of circuit with ONE path of charge. If you remove one light bulb, all the other will turn off.
A kind of circuit with TWO or MORE paths of electrical charge. If you remove one light bulb, the others will still light up because the electricity can flow
