300
A property of source charges that is related to the electric field. Is present whether or not a charged particle is there to experience it.
Electric Potential
300
A circuit that has only one path through which electricity can travel.
What is a SERIES CIRCUIT?
300
A temporary magnet formed when an electric current flows through a coil of wire. These are used in fire alarms, microwaves, hair dryers, computers, and more.

Leyden Jar
400
A 1.0-µm-diameter oil droplet (density 900 kg/m3 ) is negatively charged with the addition of 25 extra electrons. It is released from rest 2.0 mm from a very wide plane of positive charge, after which it accelerates toward the plane and collides with a speed of 3.5 m/s. What is the surface charge density of the plane?
η = 6.4 µC/m2

500
a thermodynamic quantity representing the unavailability of a system's thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system.
Entropy
500
A material that allows electricity to easily flow through it.
What is a CONDUCTOR?
500
The area around a magnet where the force of the magnet can act.
What is a MAGNETIC FIELD?
