What is an Earth Wire?
A wire that provides an electrical connection to the ground.
What is a Volmeter?
an instrument for measuring in volts the differences in potential between different points of an electrical circuit
What is a Neutral Wire?
BLUE WIRE- A wire connected to a neutral point of an electrical system (and usually also to earth).
What is a Series Circuit?
circuit composed solely of components connected in series is known as a series circuit. With ONLY 1 BRANCH.
What is Parallel Circuit?
electric current has multiple paths to flow through. More than 1 Branch.
What is an ohm?
derived unit of electrical resistance,
What is a Circuit Symbol?
Represents an object inside an electrical circuit.
What is an Electric Current?
stream of charged particles, such as electrons or ions, moving through an electrical conductor or space.
What is an Ammeter?
An instrument that measures the strength of an electric current, indicating it in amperes.
What is a Multimeter?
an electrical test instrument offering measurement of several values, usually voltage, current, and resistance
What is an Electrical Conductor?
Substance or material that allows electricity to flow through it.
What is an Electrical Circuit?
A loop
What is an Ampere?
base unit of electric current. (electrons worth of charge moving past a point in a second.)
What is an Open Circuit?
an electrical circuit in which the continuity is broken so that current does not flow.
What is Conventional Current?
: electric current flowing from positive to negative + > -|
What is an Electrical Insulator?
A substance or material that does not allow electricity to go through.
What is Resistance?
Reduced the current flow in a circuit.
What is a Closed Circuit?
a circuit without interruption, providing a continuous path through which a current can flow
What is a Live Wire?
The red or green wire that has electricity flowing and is connected to the socket.
What is a Circuit Diagram?
is a graphical representation of an electrical circuit.
What is an Electrical Charge?
is a conserved property; the net charge of an isolated system, the amount of positive charge minus the amount of negative charge, cannot change.
What is an Electric Shock?
a sudden painful feeling that you get when electricity flows through your body
What is Voltage?
the difference in electric potential between two points, the work needed per unit of charge to move a test charge between the two points.
What is a Short Circuit?
he failure of electricity to flow properly in a circuit because the wires or connections in the circuit are damaged or not connected properly.
