An opposing or retarding force offered by a component in a circuit to hinder the passage of electrical current through and is measured in ohms.
What is resistance
100
Components that sometimes act as conductors and other times act as insulators (diodes)
What are Semiconductors
100
Electrical devices are connected in line so that only one path is provided for current flow. Any break in the circuit will not allow current and will not work.
What is a Series circuit
100
It can cause circuit damage, overheating, fire or explosion. Usually unintentional as when a wire's insulation breaks down, or when another conducting material is introduced, allowing charge to flow along a different path than the intended one.
What is a Short circuit
100
A device which is made to open or close electrical pathways in an electrical circuit.
What is a switch
200
A measure of the potential energy between two places in a circuit. A unit of electrical pressure joule/coulomb of charge or energy per unit of charge
What is a Volt
200
The force (energy) which causes current to flow in an electrical circuit. It is also referred to as electromotive force or electrical potential and is measured in volts.
What is Voltage
200
An electrical component that uses energy to control current on a circuit board and is rated based on Ohms
What is a Resistor
200
A high density material that has loosely held mobile electrons that float freely from atom to atom to carry current
What is a Conductor
200
an electrical device consisting of one or more meters, used to measure the electrical quantities amps, volts or current in a circuit
What is a Mulimeter
300
A special component that allows current to flow without losing energy as heat or light
What is a Super conductor
300
The type of circuit where the value of the current is the same at all points in the electrical pathway. The whole circuit shuts down with a single break
What is a Series circuit
300
Construction workers use a thick extension cord to power their tools in order to keep this property low
What is Resistance
300
the voltage is the same across each branch because all the branch points are on the same wire.
What is a Parallel circuit
300
The fundamental property of matter responsible for electricity and magnetism. Two kinds are present.
What is Charge
400
In a circuit diagram or schematic drawing these are used to represent various components in the graphic to make it easier to draw.
What is Electrical symbols
400
Draw five basic components of a circuit diagram on the board and label
What is Switch, resistor, wire, light bulb, battery
400
What system in our body is similar to a electrical circuit
What is Our nervous system
400
If a battery has a potential energy of 1.5 Volts as it leaves the negative end of the battery and goes through a light bulb, how many volts does it have when comes back to the positive end
What is Zero
400
The type of charge that repels a positive charge and attracts a negative charge
What is Positive
500
A device located in a bathroom or near the kitchen sink in wet or damp locations that has a red button. It will disconnects the circuit in 0.03 seconds to prevent electrocution.
What is a Ground fault circuit interrupter (GFCI)
500
A device that changes electrical energy into mechanical energy
What is a Electric Motor
500
What cause current to flow. Charges always flow from a higher voltage to a lower voltage. A bird sitting on a power line with both feet on the wire is safe because there is no ___
What is a Voltage difference or drop
500
Three factors that determine resistance in a wire and explain why
