The rate at which charge passes a given point in a circuit.
What is an electric current?
100
A closed path along which charged particles move.
What are Electric Circuits?
100
A law defined by this formula R=V/I
What is Ohm's law.
200
Subatomic particle that is no charge (neutral) and contains the same mass as protons.
What is a neutron?
200
A device for making, breaking, or changing the connections in an electric circuit.
What is a switch?
200
A circuit in which all parts are connected end to end to provide a single path for the current.
What is a series circuit?
200
A material that has a resistivity of 1.59*10^-18 ohms*m
What is silver?
300
A subatomic particle that does not have the same mass as the rest of the three basic subatomic particles.
What is an electron?
300
A device to measure the potential difference.
What is a voltmeter?
300
A circuit in which the elements are connected between two points, with one of the two ends or more paths for current flow.
What is a parallel circuit?
300
The SI unit of charge.
What is a coulomb?
400
A law that states in a closed, isolated, system, the total charge of system remains constant.
What is Law of conservation of energy.
400
The opposite of conductors.
What is an insulator?

The SI derived unit for electrical energy.
What is a joule?
400
A characteristic of a material that depends on its electronic structure and temperature.
What is resistivity?
500
A law that states the size or magnitude of the electrostatic force that one point charge exerts on another point charge is directly proportional to the distance between them.
The law is given by this formula:Fe=(k*q1*q2)/r^2
What is Coulomb's Law?
500
A coil of resistance wire whose effective resistance can be varied by sliding a contact point.
What is a variable resistor?
500
Product of potential difference and current.
What is electric power?
500
A property of a material that depends on the availability of charges that are relatively free to move under the influence of an electric field.
