100
This subatomic particle carries a negative charge (-)
What is an electron?
100
This is measured in Ohms (Ω).
What is resistance?
100
THIS circuit has only one path for electrons to flow.
What is a series circuit?
100
This charged particle does NOT move.
What is a proton?
100
What is the symbol for a resistor.
200
A material in which electrons cannot move easily from place to place
What is an insulator?
200
Calculate current (I). Voltage= 10V, Resistance= 20Ω. Remember to include the correct units!
What is 1/2 or 0.5Amps?
200
This circuit allows for one light to be on while the others are off.
What is a parallel circuit?
200
Why is a short circuit dangerous?
Without enough resistance (load), the current increases and flows back into the battery, potentially causing fires.
200
You can increase the voltage in a circuit by adding this component. Draw the symbol.
300
Electrons flow freely through metals such as copper, gold, sliver, and aluminum. What type of material is this?
What is a conductor?
300
Find the current through a 12-ohm resistive circuit when 24 volts is applied.
What is 2Amps?
300
Current is divided as paths split off.
What a parallel circuit?
300
Like charges ______, and opposite charges ______.
What is repel and attract?
300
The series circuit with 2 lightbulbs and a switch.
400
THIS component is used to supply energy to an electric circuit by converting chemical energy into electric potential energy.
What is a battery
400
What is the resistance of a heating element that allows 15 Amps to flow when 440 V is applied to it?
What is a 29.3 Ohms?
400
Describe the trend for current and voltage in a series circuit.
Same current flows through the entire circuit.
Voltage drops at each component.
400
What are the parts of a battery, and how is a wet cell different from a dry cell?
Two metal electrodes and electrolyte - dry cell = paste, wet cell = liquid
400
Draw a circuit where a slow motor and dim lightbulb are both controlled by a switch.
Series circuit with battery, lightbulb, switch and motor.
500
A person may acquire a build up of this type of electricity using friction, conduction or induction.
What is build up of static electricity?
500
How much voltage is required to make 15 Amps flow through a 7.5 ohm resistance?
What is 112.5V?
500
What is the trend for current and resistance in a parallel circuit?
Current: splits unequally between branches (least resistance = highest current)
Resistance: total resistance in a parallel circuit is less than the smallest of the individual resistances
500
Name 6 methods of generating electrical energy.
Hydro, Nuclear, Biomass, Tide, Wave, Coal, Geothermal, Solar, Wind
500
Draw a circuit with three light bulbs where a switch controls 1 light bulb. If you remove a specific light bulb, all the light bulbs will turn off.
Smaller than any one of the individual components.
