write a formula to show relationship between current and time
Answers
Answer:
The time rate of flow of electric charge, in the direction that a positive moving charge would take and having magnitude equal to the quantity of charge per unit time is called Current. Electrical charge is measured in coulomb, C.
Answer:
Explanation:
1. The time rate of flow of electric charge, in the direction that a positive moving charge would take and having magnitude equal to the quantity of charge per unit time is called Current.
The relation between current, charge and time is
Electrical charge is measured in coulomb, C. The amount of electrical charge that moves in a circuit depends on the current flow and how long it flows for.
The equation below shows the relationship between charge, current and time:charge (coulomb, C) = current (ampere, A) × time (second, s)
2.The SI unit of current is Ampere. 1 ampere is the constant current that will produce an attractive force of 2 × 10^−7 newton per metre of length between two straight, parallel conductors of infinite length and negligible circular cross section placed one metre apart in a vacuum.
