Circuits
The term for the wires in an electric circuit.
What are conductors?
A circuit that is built without a load.
What is a short circuit?
The symbol and unit used for voltage.
What is V and the volt?
The analogous component for water pressure.
What is voltage?
The purpose of a circuit breaker.
What is to interrupt the flow of current if it gets dangerously high?
The term for the part of the circuit that converts electrical energy into other forms of energy.
What is a load?
The purpose of the plastic cover on electrical wires.
What is to act as an insulator?
The symbol and unit for current.
What is I and the ampere?
The analogous component for current.
What is flow rate?
Draw a circuit diagram showing how to control 3 different lights individually, or all of them with a "master" switch.
(see diagram)
The term for the part of the electric circuit that supplies the voltage.
What is the source?
The reason why a bird doesn't get electrocuted when it sits on a transmission line.
What is not providing a path to the ground.
The circuit diagram symbol for a resistor/load.
(Draw on board)
The analogous component for resistance?
What is pipe diameter/size?
The reason why power is transmitted using high-voltage transmission lines.
What is to reduce current? (power losses occur based on P = I2R)
The device used to measure electric potential difference across a load.
What is a voltmeter?
The result of too much current flowing through a small wire.
What is overheating/fire?
The symbol and unit for resistance.
What is R and the ohm?
How the current responds if the voltage is increased and resistance stays constant (+ explain using analogy).
What is that current increases? (Higher water pressure and same pipe diameter means greater flow rate).
The way you could create a fruit battery in the lab.
This device is used to measure the current in an electric circuit.
What is an ammeter (or multimeter)?
The reason why an ammeter can be damaged if connected to a circuit with no load.
(Long explanation)
The mathematical law used to analyze electric circuits.
What is Ohm's Law?
How the current responds if the resistance is increased and voltage stays constant (+ explain using analogy).
What is that the current decreases? (With constant water pressure, if the pipe diameter is decreased then the flow rate increases)
A circuit diagram where 4 lights are controlled by 3 switches, such that 2 are operated together and 2 are operated separately.
