Question

If 20 Coulombs of charge passes a point in a circuit in 1 second, what is the value of the current flowing?

A.

20 Ampere

B.

5 Ampere

C.

10 Ampere

D.

15 Ampere

Correct option is A

The correct answer is (a) 20 Ampere.
· Current (I) is defined as the rate of flow of electric charge and is calculated using the formula:
I=
where:
· I is the current in amperes (A),
· Q is the charge in coulombs (C), and
· t is the time in seconds (s).
· In this case:
· Q=20 Coulombs
· t=1second
Applying the formula:
I==20A
· Hence, the current flowing through the circuit is 20 Amperes.
Information Booster:
· Current (I): The flow of electric charge, measured in amperes (A).
· Coulomb (C): The unit of electric charge.
· Ampere (A): The unit of current, defined as one coulomb per second.
· Formula: I=Qt​, where Q is charge in coulombs and t is time in seconds.
· Electric Charge Flow: Current is the movement of electric charges through a conductor, such as a wire.
