300

Should a circuit breaker be connected in series or parallel to the circuit that it is protecting?

What is series?

400
like charges
What is repel?
400
measure of how much electric energy an electron in a circuit can gain from a battery
What is voltage?
400
For safety in homes and buildings these limit the amount of current in the wiring.

What causes lightning?

What is a buildup between opposite charges becomes so great that the insulating capacity of air breaks down and there is a rapid discharge of electricity.

500
the length and thickness of a wire will affect this

500
All objects exert this
What is electric force?
500

How can you quickly determine whether a string of light is wired in series or parallel?

Unscrew a bulb and if the entire stringer of goes out, then it's wired in series, but if all the other light remain let then it's wired in parallel.
