100
The physical property of matter that causes it to experience a force when placed in an electromagnetic field.
What is Electric Charge?
100
An electromotive force or potential difference expressed in volts.
What is voltage?
100
A path in which electrons from a voltage or current source flow. Electric current flow in a closed path is called an electric circuit. The point where those electrons enter an electrical circuit is called the "source" of electrons.
What is electric circuit?
100
The branch of physics and technology concerned with the design of circuits using transistors and microchips, and with the behavior and movement of electrons in a semiconductor, conductor, vacuum, or gas.
What is electronics?
100
Consists of three semiconductors, either p-n-p or n-p-n. Current can’t flow through a transistor unless a small amount of current is applied to the center semiconductor (through the base).
What is Transistor?
200
A region around a charged particle or object within which a force would be exerted on other charged particles or objects.
What is Electric Field
200
The rate at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second. Electric power is usually produced by electric generators, but can also be supplied by sources such as electric batteries.
What is electric power?
200
A solid substance that has a conductivity between that of an insulator and that of most metals, either due to the addition of an impurity or because of temperature effects. Devices made of semiconductors, notably silicon, are essential components of most electronic circuits.
What is semiconductor?
200
A tiny, flat piece of silicon that consists of layers of electronic components such as transistors.
What is Integrated Circuit (Microchip)?
300
Stating that the total electric charge of a closed system remains constant over time, regardless of other possible changes within the system.
What is law of conservation of charge?
300
A law relating the voltage difference between two points, the electric current flowing between them, and the resistance of the path of the current. Mathematically, the law states that V = IR, where V is the voltage difference, I is the current in amperes, and R is the resistance in ohms.
What is Ohm’s law?
300
A closed circuit in which the current divides into two or more paths before recombining to complete the circuit. Each load connected in a separate path receives the full circuit voltage, and the total circuit current is equal to the sum of the individual branch currents.
What is parallel circuit?
300
An electric current that represents information.
What is electronic signals?
300
Typically found in bathrooms and kitchens where the use of water poses a risk of shock.
What is GFCI Outlet?
400
The sudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown.
What is static discharge?
400
A material whose internal electric charges do not flow freely, and therefore make it nearly impossible to conduct an electric current under the influence of an electric field.
What is electric insulator?
400
A closed circuit in which the current follows one path, as opposed to a parallel circuit where the circuit is divided into two or more paths. In a series circuit, the current through each load is the same and the total voltage across the circuit is the sum of the voltages across each load.
What is series circuit?
400
Any basic discrete device or physical entity in an electronic system used to affect electrons or their associated fields.
What is electronic component?
400
A switch that automatically opens a circuit if too much current flow through it.
What is Circuit Breaker?
500
A stationary electric charge, typically produced by friction, that causes sparks or crackling or the attraction of dust or hair.
What is static electricity?
500
A flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in a plasma.
What is electric current?
500
Generally used on metal appliances.
What is Three-Prong Plug?
500
Consists of a p-type and an n-type semicon-ductor placed side by side.
What is Diode?
500
A substance in which electrical charge carriers, usually electrons, move easily from atom to atom with the application of voltage. Conductivity, in general, is the capacity to transmit something, such as electricity or heat.
What is electric conductor?
