formulas of electric current through the conductor
Answers
Answer:
Electric current = I = V/R or √(W/Rt) or Q/t
hope it helps.....
Answer:
The conventional direction of electric current is taken as opposed to the direction of flow of electrons. If a charge Q flows through the cross-section of a conductor in time t, the current I then I=Q/t. The S.I unit of charge is coulomb and measurement of electric current happens in units of coulomb per second which is ‘ampere’. The current flows from the negative terminal to the positive terminal of the cell.
This is a simple electric circuit. It has a lamp, a switch, and a cell.
In a torch, the battery provides the flow of charges which means the bulb in the torch glows due to the electric current. What does a switch do? The switch creates a conducting link between the cell and the bulb. If the circuit breaks, then the current stops flowing immediately and the bulb does not glow.
