Electricity
100
the flow of electricity
What is an electric current
100
the force that causes the free electrons to move from one atom to another
What is voltage
100
the tendency an object will try to stop the electricity from flowing
What is resistance
200
a dry cell battery keeps its electrolytes in a low moisture paste while a wet cell battery is operated by a liquid solution.
what is the difference between a dry cell battery and a wet cell battery
200
voltage measures the electric pressure
What does voltage measure
200
resistance is measure in ohm's
what do you measure resistance in
300
a lead acid battery uses a chemical reaction to produce a voltage
What is a lead acid battery
300
this is the difference between 2 points
What is voltage difference
300
by doing this it increases the resistance
what happens when you make a wire longer thinner or hotter
400
I is amps V is volts and R is resistance
What does the equation I=V/R stand for
400
a circuit is a pathway for wires
What do you use a circuit for
400
this will stop the charges from flowing through the wire since it would not be hooked up to any thing
what happens if a wall socket is not hooked up to wires
500
currents passing through a conductor is the same as voltage/resistance
What does ohm's law state
500
the electrons give it power to work
What happens to a device when electrons get to it
500
charges flow from high to low
how do charges flow
