what is electic current state its formula and unit Explain direction of electric current in circuit.
Answers
Answer:
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.
Explanation:
Electric current is the rate of change of electric charge through a circuit. This electric current is related to the voltage and resistance of the circuit. Using Ohm's law, we can represent as the formula: I= \frac {V}{R}
A convention for direction
Scientists agree to use a convention which shows the direction of the electric charge flow (the current) in a circuit as being from the positive terminal of the battery towards the negative terminal.
Answer:
electric current is the flow of electrons in an specific direction
Explanation:
it's unit is ampere
it's direction is opposite to flow of electrons
