These are the first 2 assignments incorporated together for unit 15 Electrical Circuits BTEC Applied Science. These assignments have been awarded a Distinction grade ( that’s why is a RESUBMISSION written) Bibliography can be found at the end and please do not copy, use them as a guide only. Good luck!

Definitions:
Terms Meaning
Current, I defines the electric charges that are moved due to the flow of electric current.
(ampere) = the electrical charge flow when there is a source that provides potential
difference and a closed circuit. Measured in amperes. The flow of charge, C =
current, A x time, s. the value of the current in a closed loop does not change.
Current Is equal when change divides by the time taken.

potential the amount of work per unit charge done by a component. This also applies to
difference, V a power source. The energy gets transferred using the charge carriers that pass
(volt) = through the components in the circuit. The voltmeter is used to measure
potential diff. the equation is V= I x R therefore the potential diff is the same as
the current multiplied by resistance. A potential difference describes how one
volt is equal to one joule that is being used by one coulomb of charge.

electrical a physical property of particles that shows how they are affected by an
charge, C/Q electrical field. Can be positive, negative or zero. The current of one amp is
(coulomb) = equal to one coulomb that passes through a point per seconds. Q=I x t.

resistance, R property of something that tries to slow down/resist the current. A bigger
(ohm) = resistance causes a smaller current to pass through a component in a circuit.
The equation is: V= I x R

conductance, measures how easily the flow of charge can travel through a material. It is the
1/R (Siemen) = inverse of resistance as R= 1/G or/and G=1/R. siemens can be also equal one
ampere per volt.

electrical rate at which the electrical energy is used through a circuit. Can be also
power, SI/P described as how much electrical work done is made per unit time. Power will
