Circuits
True or False: All you need to light a light bulb is a copper wire, a battery and a light bulb.
What is true?
This unit measures electric potential difference and electromotive force.
What is a volt?
Output is only on if both inputs are on
AND Gate
Also known as an electrochemical cell, it transforms the energy from a chemical reaction into electrical energy.
What is a battery?
What is the unit of current
Amperage or Amps
A circuit that only has one path in which electricity can travel.
What is a series circuit?
This basic circuit component resists the flow of electric current.
What is a resistor?
Inverts the signal
NOT gate
Used to turn a circuit on or off
Switch
What is the formula for Ohm's Law?
V = I x R
A drawing used by electrical engineers that uses symbols to represent a circuit.
What is a schematic diagram?
This device stores electric charge and consists of two conductors separated by an insulator.
What is a capacitor?
Has output when only 1 input is on. If both are on or off the output is off.
XOR gate
What unit measures power?
Watt
What does Kirchhoff’s Voltage Law state?
The sum of all voltages around a closed loop equals 0
The component in a circuit that does not allow electricity to pass through.
What is an insulator?
This law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
What is Ohm's Law?
The opposite of an AND gate.
NAND Gate
What does LED stand for?
Light Emitting Diode
What does Kirchoff's current Law State?
Current coming in is equal to the total current going out!
A copper penny could be used as a ____________ in an electrical circuit.
What is a conductor?
Uses the abbreviation AC. The electrons move back and forth in a regular pattern.
What is alternating current?
Has output only if both inputs are off or on. If one input is on, there is no output.
XNOR
A device that allows electric current to flow in only one direction.
What is a diode?
In a _____________, there is more than one path or branch for current and the voltage is the same everywhere
What is Parallel circuit
