What is mechanical energy?
The combination of energy in motion (kinetic) and position (potential)
What is electrical energy?
Energy that involves an electric current
Batteries have two metals, that we call what?
TRUE or FALSE
Energy cannot be changed from one form to another
A battery turns chemical energy to _______ energy
Electrical
What tool is used to measure small currents?
A Galvanometer
Alternating currents is the flow of an induced current that may be constant OR may change direction
TRUE or FALSE
TRUE
An electric current in a wire produces what? (This is the region around the current)
Magnetic field
Give an example of an AC (alternating current)
electricity flowing through your house, school, work building, etc.
What is one way we are charged for electricity?
The amount of watts used per hour.
Contrast a wet cell and a dry cell
Wet- electrolytes are a liquid (car battery)
Dry- electrolytes are not necessarily dry, but more of a paste rather than a liquid (standard battery)
Give an example of a direct current
energy stored in batteries, electronics, vehicles
How are electric motors different than generators?
Electric motor- uses electricity to produce motion
Generator- uses motion to produce electricity
Why is it important to have general knowledge about electricity?
Compare & Contrast alternating and direct currents
Similar- both are forms of circuits/energy flow
Difference- Alternating: the flow of energy can be direct, or reverse direction; Direct: flow of energy is in one direction
