1) Electric Current: The rate of flow of electric
charges through a conductor or circuit.
2) Electric Circuit: The electric circuits are
closed-loop or paths, forming a network of electrical components where electrons
can flow.
3) Electric Potential: The amount of work needed to move
a unit charge from a reference point to a specific point against an
electric field..
4) Electric Resistance: The property of a material that
resists the flow of electric current.
5) Ohm's Law: At constant temperature, the
current flowing through a conductor is directly proportional to the potential
difference across its ends .
6) Electric Power: The rate at which electrical energy
is used or produced in an electric circuit.
P = V I, where P is power, V is
voltage and I is current.
7) Series Circuit: A circuit where all components
are connected in a single path, allowing the same current to flow through each
component.
8)
Parallel Circuit: A circuit where multiple
components are connected in separate paths, allowing different currents to flow
through each branch.
9)
Electric Fuse: A safety device used to protect
electrical circuits from excessive current by melting and breaking the circuit.
10)
Heating Effect of Electric Current: The phenomenon where electric
current passing through a conductor produces heat.
11)
Electric Cell: A device that converts chemical
energy into electrical energy.
12)
Electric Battery: A combination of two or more
cells connected in series or parallel to provide a higher voltage or
longer-lasting power source.
13)
Electric Conductors: Materials that allow electric
charges to flow freely through them.
14)
Electric Insulators: Materials that do not allow
electric charges to flow easily and effectively block the flow of electric
current.
15)
Joule's Law: The amount of heat produced in a
conductor is directly proportional to the square of the current passing through
it, the resistance of the conductor, and the time for which the current flows.
16)
Electric Potential Difference: The difference in electric
potential between two points in an electric field, measured in volts.
17)
Ammeter: A device used to measure the
electric current flowing through a circuit, usually connected in series.
18)
Voltmeter: A device used to measure the
electric potential difference (voltage) between two points in a circuit,
usually connected in parallel.
19)
Short Circuit: A fault in an electric circuit
that occurs when a low-resistance path is unintentionally created, causing a
very high current flow.
