Flow in an electric circuit

Path for electric current with electromotive force applied

Relationship of EMF, Current, and Resistance

Flows in one direction; uniform strength; battery/dry cell; either continuous or pulsating

Reverses direction of flow at regular intervals; reverses in direction; 60 cps frequency

Reverse half of the cycle is "turned around"; referred to as single-phase full-wave DC

Reverse half of the cycle is blocked out entirely; referred to as pulsating direct current

Simple current; alternating in direction

Three separate currents following separate sine curves; at least three conductors are required

Utilizing short circuited AC or condensed discharged DC

Applies high fields for brief periods.

Slight variation of pulsed current magnetization.

Causes movement of electricity in a conductor

Electrical layout

Complete; continuous path

Broken; incomplete; disconnected

Has two or more paths for current to flow through

Voltage is the same across each component of the circuit

The sum of the current through each path is equal to the total current that flows from the source.

Has more than one resistor, but only one path through which electricity flows

Bridging; an electrical circuit that allows a current to travel along an unintended path with no or very low electrical impedance.

Opposite of an open circuit

Results in an excessive current flowing through the circuit.

Circuit branching

Pressure or force; unit of electrical pressure or force

Makes electricity flow through a wire

Directly proportional to electric flow

Inherent in wires; unit used to measure the magnitude of an electric current

Current-carrying capacity (without undue heating)

Inherent in insulators; unit used to measure resistance to electricty.

Industrial facility for generating electric power

Method of convertimg solar energy into direct current electricity using semiconducting materials

Converts the wind's kinetic energy into electrical energy.

Potential of a chemical substance to undergo a transformation through chemical reaction

Capture the energy of falling water to generate electricity

A thermal power station in which the heat source is a nuclear reactor.

Use heat deep in the earth to generate electricity

Wood waste or other waste is burned to produce electricity

Burns fossil fuel to produce electricity

most abundant fossil fuel on the planet; widely used as the source of energy in thermal power stations

Naturally occurring hydrocarbon gas mixture consisting primarily of methane

Oil fired power plant

Rate of power; power consumption; depends on both potential and current.
