What is one way that Ontario generates power?
Solar, wind, nuclear, hydro, bio fuel, etc.
100
What is the rule for a closed loop of any circuit?
There cannot be any gaps
100
What is a series circuit
A circuit that is connected all in a line or row.
100
Why are parallel circuits called parallel?
The circuits are literally parallel to one another.
200
What task does a switch perform
It can open and close the circuit
200
What is one requirement for generating electricity
A generator
200
What happens when there is not electrical load?
A fire could start due to too much electricity.
200
What happens if the switch is open?
The bulb will not light up.

What will happen if a battery is placed backwards into a circuit?
The circuit may catch on fire
500
Which battery is more powerful a 1.5V or a 9V?
9V
500
What happens if a light bulb is removed from a series circuit?
All of the bulbs will turn off as there is now a gap in the circuit
