INDUSTRIAL TECHNOLOGY TEST WITH CORRECT
ANSWERS #1
Resistor - correct answer opposition to electron flow in a circuit.
Photo resistor - correct answer A device that changes resistance as light intensity
varies.
Diode - correct answer a semiconductor device that allows the current to flow in only
one direction.
LED - correct answer light emitting diode. Converts energy directly into light energy.
Conductor - correct answer a material that allows electrons to flow through easily.
Current - correct answer the amount of electricity flowing through the circuit.(measured
in amps)
Voltage - correct answer the amount of pressure pushing the electricity.(measured in
volts)
Path of least resistance - correct answer electricity will flow through the path that is the
easiest
Press switch and slide switch - correct answer allows current to flow or not flow when
the press is moved
Direct current (DC) - correct answer current that only flows in one direction (battery)
Short circuit - correct answer very low resistance paths that keep going across the
batteries that will drain them quickly and possibly damage the equipment.
Series circuit - correct answer a circuit that has only one path for the current to flow
through
Parallel circuit - correct answer 2 or more paths for a current to flow through
Insulator - correct answer a material that stops the flow of electrons.(electrons, rubber,
wood, ceramic)
Fuse - correct answer a device designed to fail
Battery - correct answer electrons that flow from the negative terminal to the positive
terminal
