Vocabulary
Something that impedes the flow of electrons.
What is resistance?
Voltage is equal to current multiplied by resistance.
What is Ohm's Law?
This can store electrical charge.
What is a capacitor?
When the cathode of an LED is connected to the positive side of a circuit this occurs.
What is not light up?
A conductor that allows electrons to flow.
What is a wire?
Like charges repel and unlike charges attract.
What is the Law of Charges?
This allows current to flow in only one direction.
What is a diode?
When a correctly installed incandescent bulb does not light up.
What is a burned out filament?
The pressure that makes electrons flow.
What is voltage?
Power is equal to voltage multiplied by current.
What is the Watt's Law?
Allowing current to flow in only one direction, when installed correctly, this emits light.
What is a LED?
When the potential across a battery is zero.
What is a dead battery?
A problem that allows electrons to flow unimpeded and through an unexpected pathway.
What is a short?
When a conductor is near a moving magnetic field, electrons flow through the conductor.
What is Faraday's Law?
A variable resistor is known as a what?
What is a potentiometer?
When the current flow to a battery is infinity.
What is a short circuit?
A circuit that does not allow electrons to flow.
What is an open circuit?
Current in a node must equal current out of the node.
What is Kirchoff's Law?
An component that acts as a switch when a minimum amount of current is allowed to flow to the base.
What is an NPN Transistor?
When a circuit does not turn on, it is usually caused by this.
What is an open circuit?
