By definition, electric current is the amount of electric charge that flows through the cross-section of a conductor in a given unit of time:

`I = (Delta Q)/(Delta t)`

In SI (International System of units) the charge (Q ) is measured in Coulombs, and the time is measured in...

By definition, electric current is the amount of electric charge that flows through the cross-section of a conductor in a given unit of time:

`I = (Delta Q)/(Delta t)`

In SI (International System of units) the charge (Q) is measured in Coulombs, and the time is measured in seconds. The unit for current then equals 1 Coulomb/second, and it is called 1 Ampere, or, sometimes, 1 amp.

In this question, the amount of charge flowing through the heating element is

`Delta Q = 2400 C` in `Delta t = 200 s` . This means the current flowing through the heating element is

`I = 2400/200 A = 12 A` .

Please check out the reference website for the further discussion of the definition and units of measurement of electric current.

The current flowing through heating element is 12 A (Amps)
