Static Electricity
Particle that has a negative charge.
What is an electron?
The "official" term for the wires in an electric circuit?
What are conductors or connectors?
The resistance when a 120V source has a current of 12 Amps.
What is 10 Ohms?
The symbol for a bulb
What is...
Decreasing the diameter of the wire OR increasing the length of the wire will do this to the resistance in a circuit
Increase resistance
How do neutral objects become charged?
The loss or gain of electrons.
If a circuit is correctly put together, a load will not operate if the switch is
What is open?
The formula used to calculate current.
What is V/R?
Draw the symbol for a fuse
fuse
Material that allows electricity to flow easily through it is called
What is a conductor?
The largest form of static electricity (think weather)
What is lightning?
The part of a circuit that controls the movement of electrons (whether they move or not)
What is a switch?
The amount of current when a 120V source has a load with a resistance of 24 Ohms.
What is 5 A?
Draw the symbol for a battery
4 lines total
Increasing the number of bulbs in a parallel circuit (each on their own branch) will do this to the brightness of the bulbs?
Nothing. They will remain the same level of brightness.
A negatively charged balloon and a neutral wall will...
What is attract?
The 4 main parts of a circuit
What are a control device (switch), load, electrical source, and conductors (wires)?
If resistance in a circuit is increased, what happens to the current?
It decreases
Draw the symbol for the device used to variably control resistance (like a dimmer switch)
variable resistor
The path that electricity follows called
What is a circuit?
If static electricity is the buildup of electrons, what is current electricity?
The flow of electrons.
This device is used to measure the voltage in an electric circuit
What is a voltmeter?
The voltage when a 6A current has 20 ohms of resistance.
What is 120V?
The symbol for the device used to slow the movement of electrons
Resistor
The difference between a series circuit and a parallel circuit
What is...
Series: electrons only have one path to follow
Parallel: electrons have more than one path to follow
