Current is the rate of flow of electrons per unit time and is measured in amperes (A). A coulomb (C) is the quantity of electricity conveyed in one second by a current of one ampere.
Why does current in an electric circuit create heat?
current is naturally hot |
|
voltage is naturally hot |
|
the wire in the circuit burns when current passes through |
|
heat is created when the current overcomes resistance in the wire |
