Short Answer
Illustrated Challenge "?"
100
Current
The continuous flow of electrons
100
Voltage
The potential to push electrons
100
Describe one way to protect the parts of an electrical circuit from a surge of current.
A fuse or a circuit breaker can be used
100
What would be the output for this gate be?
1
200
Static electricity
A stationary electrical charge
200
Parallel
A circuit with multiple paths for electrons
200
Describe how lightning is formed.
Friction between air, water drops, ice and hail creates ionized particles, causing charges to accumulate at the tops and bottoms of the clouds. When the electrical difference is great enough, a bolt of electricity moves from cloud to cloud or cloud to ground.
200
What would be the output for this gate be?
0
300
Insulator
Material that resists the flow of electrons
300
Serial
A circuit with only one path for electrons
300
Describe the difference between a battery and a power station.
Battery—chemical reaction resulting in extra electrons;
Power Station—heats water to turn a turbine that turns a coil inside a magnetic field thus generating electricity
300
What is the voltage of the battery if the current flowing in the circuit is 2 amps?
V = IR = (2) (150 + 50) = 400 Volts.
400
Conductor
Material that allows electrons to flow freely
400
Switch
Device to control the flow of electrons by opening and closing the circuit
400
Describe how a light switch works.
A switch completes a circuit allowing current to flow when the light is on, opens or breaks the circuit when the light is off.
400
In the circuit below, what is the power of the light bulb if the electricity coming into the house is 120 volts and the current is 0.5 amps?
P = IV = 120 x 0.5 = 60 Watts.
500
Ion
A charged particle
500
Resistance
The degree to which a substance or device opposes the passage of an electric current.
500
Describe one use of static electricity today.
Static electricity is used in laser printers to ionize the paper, and it is used to ionize pollutants to more easily remove them from the air.
500
In the circuit below, if the battery supplies 6 volts and the resistor is 100 ohms, how much current will flow in the circuit?
I = V/R = 6/100 = 0.06 Amps
