What is found in the nucleus of an atom ?
What are protons and neutrons
Electric circuit in which there is only one path for electrons to flow.
What is a series circuit?
Requires an internal power source and uses the device being checked as the load to produce the magnetic field.
What is an analog ohmmeter?
A load that converts electrical energy into rotating mechanical energy.
What is a motor?
Ratio that compares true power to the apparent power.
What is power factor ?
Electrons possess what electrical charge ?
What is negative?
Motors, light bulbs,electric heaters are all examples.
What is an electric load ?
Fundamental principle of electricity that digital meters use to measure and calculate electrical characteristics.
What is Ohm's law ?
Coil, contacts, mechanical linkage are the components
What is a contactor ?
Color wire typically used for neutral.
What is white ?
Materials in which atoms contain free electrons that can easily be knocked out of their orbits.
What are conductors?
How control circuits are typically connected with the loads they control.
What is series?
Used to measure the amount of current flow in an electric circuit.
What is an ammeter ?
Part of a relay that is an electric load.
What is a coil ?
Green or bare wire in some electrical circuits not intended to carry current usually.
What is a ground ?
Like charges repel, positive charged particles are attracted to negatively charged particles
What is the law of electric charges ?
The amount of electrical pressure that is used or lost through a conductor.
What is voltage drop ?
This can be done when using a clamp on ammeter with a small current draw to amplify the reading on amperage, math is involved.
What is coiling the conductor?
Simplest type of overload device.
What is a fuse ?
Most common frequency in our country
What is 60Hz
The flow of electrons from one object to another in which prolonged or steady current flow is not possible.
What is static electricity?
Circuit used to combine control circuits with circuits that supply power.
What is a series-parallel circuit ?
Used to measure electromotive force.
What is a voltmeter.
Test says Wattmeter even though this is wrong.
Factual, installation, schematic are all types of this.
What is a wiring diagram ?
Used to measure true power of an alternating current circuit.
What is a wattmeter ?
