Charge to Current Calculator:
Enter the values of charge, Q(C) and change in time, dT(s) to determine the value of Current, I(A).
Charge to Current Formula:
Current is defined as the rate of flow of electric charge. In electrical and electronic systems, understanding the flow of charge is essential for designing and analyzing circuits.
Charge refers to the quantity of electricity obtained by an object. Time interval is the duration over which the charge flows.
This formula states that the current is equal to the total charge divided by the time period over which that charge flows. It essentially describes how quickly charge is moving in a circuit.
A higher value of current can result from either a larger amount of charge moving through a point in a given time, or the same amount of charge moving in a shorter amount of time.
The equation also implicitly relies on the principle of charge conservation; the amount of charge entering a point in a closed circuit over a period must equal the amount of charge leaving it, assuming no storage of charge within that part of the circuit.
Current, I(A) in amperes is calculated by dividing the charge, Q(C) in coulombs by change in time, dT(s) in seconds.
Current, I(A) = Q(C) / dT(s)
I(A) = current in amperes, A.
Q(C) = charge in coulombs, C.
dT(s) = change in time in seconds, s.
Charge to Current Calculation:
- Calculate the current when a charge of 15 coulombs flows through a conductor in 3 seconds.
Given: Q(C) = 15C, dT(s) = 3s.
Current, I(A) = Q(C) / dT(s)
I(A) = 15 / 3
I(A) = 5A.
- Determine the time interval needed for a charge of 40 coulombs to flow if the current is 8 amperes.
Given: Q(C) = 40C, I(A) = 8A.
Current, I(A) = Q(C) / dT(s)
dT(s) = Q(C) / I(A)
dT(s) = 40 / 8
dT(s) = 5s.
