Electrostatics, Voltage, and Capacitance
A physical property of an object that causes it to be attracted toward or repelled from another charged object. Each charged object generates and is influenced by a force called an electromagnetic force.
This is the SI unit for current, which is equal to 1 C/s.
This is an electrical component used to store energy by separating electric charge onto two opposing plates.
This is the process by which an electrically charged object brought near a neutral object creates a charge in that object.
This term represents the changing of a light ray’s direction when it passes through variations in matter.
This term is one of the four fundamental forces of nature. The ______ force consists of static electricity, moving electricity and magnetism.
This is the unit of resistance, given by = 1 V/A.
This is a set of two rules, based on conservation of charge and energy, governing current and changes in potential in an electric circuit.
G, a unit of the magnetic field strength; 1 G = 10–4 T.
This term represents the spreading of white light into its full spectrum of wavelengths.
This law is the mathematical equation used to calculate the electrostatic force vector between two charged particles.
This term represents an intrinsic property of a material, independent of its shape or size, directly proportional to the resistance, denoted by ρ.
This term represents the amount of resistance within the voltage source.
This is an object that is temporarily magnetic when an electrical current is passed through it.
This is the basic unit of matter, which consists of a central, positively charged nucleus surrounded by negatively charged electrons.
This term represents the amount of charge stored per unit volt.
This is the rate at which electrical energy is supplied by a source or dissipated by a device. It is the product of current times voltage.
Current is the flow of charge; thus, whatever charge flows into the _____ must flow out. The rule can be stated I1 = I2 + I3.
This is a device used to convert mechanical work into electric energy. It induces an emf by rotating a coil in a magnetic field.
This type of motion represents the continuous random movement of particles of matter suspended in a liquid or gas.
This is the energy given to a fundamental charge accelerated through a potential difference of one volt.
This is the current that fluctuates sinusoidally with time, expressed as I = I0 sin 2πft, where I is the current at time t, I0 is the peak current, and f is the frequency in hertz.
Whatever energy is supplied by emf must be transferred into other forms by devices in the _____, since there are no other ways in which energy can be transferred into or out of.
This is the amount of magnetic field going through a particular area, calculated with Φ = BA cos θ where B is the magnetic field strength over an area A at an angle θ with the perpendicular to the area.
This states that no two electrons can have the same set of quantum numbers. That is, no two electrons can be in the same state.
