Electricity is movements of charge round a circuit.

Which is called electric current.

Electric current is the movement of

negative charges (electrons) in a

circuit.

Symbol: I

Unit: current of 1 A is 1 C of charge transferred in 1 s. Current in Amps (A), time in seconds (s). Charge transferred in coulombs (C)

Equation: (Attached above)

Rearrangement: Q=It

t=Q/I

Electric current is the net flow of charge carriers past a given point in an electric circuit in a given period of time

. The unit for electric current is ampere (A), which is equivalent to one coulomb of charge per second (s)

where I is the electric current, Q is the charge, and t is the time ^.The instrument used to measure electric current is called an ammeter. An ammeter is connected in series with the circuit element whose current we want to measure

Series circuit: A series circuit is one in which the components are connected end-to-end, forming a single path for the current. The current is the same in every component, but the voltage is divided among them.

Parallel circuit: A parallel circuit is one in which the components are connected across each other, forming multiple paths for the current. The voltage is the same in every component, but the current is divided among them. The total resistance of a parallel circuit is the reciprocal of the sum of the reciprocals of the individual resistances.

The SI unit of electric current is Ampere and is denoted by the letter A. Ampere is defined as one coulomb of charge moving past a point in one second. If there are 6.241 x 10¹⁸ electrons flowing through our frame in one second, then the electrical current flowing through it is 'One Ampere.

Electric current is measured in units of amperes; the symbol for the ampere is A. One ampere is equal to one coulomb passing a point in a wire in one second. We can calculate current, 𝐼 , using the formula 𝐼 = 𝑄 𝑡 , where 𝑄 represents an amount of charge passing a point in an amount of time, 𝑡 .
