the study of the forces acting between charges, called electricity at rest

the study of the forms of energy associated with the flow of charge

the study of the forces acting between charges in motion

subatomic particle found in the nucleus of every atom

does not refer to a third type of charge, but to the presence in a region of positive and negative charges in equal amount.

the transfer by contact with an already charged object

is the separation of charge when near an already charged object with no physical contact

imaginary region in space surrounding a charged object

imaginary region in space surrounding a charged object

The electric field has two frequently used

continuous flow of charges through a material

the difference in electric potential between two points, which is defined as the work needed per unit of charge to move a test charge between the two points

another call for voltage

The positive and negative terminals are called

device that measures the voltage or potential between two points.

measure of the opposition to current flow in an electrical circuit

passive two-terminal electrical component that implements electrical resistance as a circuit element

defined as flow of electrons in wire, or the rate of flow of charges thru a wire

device that measures the current through a material in a circuit.

is the rate of work done per unit time, at which electrical energy is transferred by an electric circuit

is the work done by moving electric charges

The meter used to measure the energy that we consume at home is called the

defined as a path for current to flow

like the gate valve and the hose like the connecting wires

are a graphical representations of an electrical circuit

diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations

consisting of just one battery and one load resistance are very simple to analyze, but they are not often found in practical applications.

in this circuit connection the components are connected end-to-end in a line to form a single path through which current can flow.

in this circuit connection, all components are connected across each other’s leads

These circuits combine the characteristics of both series and parallel.

These laws are used to analyze and solve circuits that cannot be reduced by the rules of combining resistors in series and in parallel

The sum of all currents entering a junction must be equal to the sum of all currents leaving the junction”

states that the algebraic sum of potential differences, including voltage supplied by the voltage sources and resistive elements, in any loop must be equal to zero.

in a parallel circuit is a path for electric current formed by one of the load components (such as a resistor).

used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.
