Answer 2

Answer:

A charge of 420 C is flowing through a circuit for 60 seconds then the current in the circuit​ is 7A.

Explanation:

The rate of charge change is defined as current. As a result, charge is defined as the current that flows through a material in one second (unit time). The amount of charge flowing through the conducting wire, as well as the time in minutes, are given in the question. We can find the value of the current flowing through the wire by applying the appropriate formula and making the necessary conversions. Because one ampere equals one coulomb per second, we must convert time to seconds to obtain the charge value in coulomb.

Electrical work is done and energy is transferred when current flows.

The amount of charge passing a point in the circuit can be calculated using the equation

charge = current × time

Q= I× t

This is when:

charge (Q) is measured in coulombs (C)

current (I) is measured in amps (A)

Time = 60s

Charge Q= 420 C

$Current I = \frac{Q}{T} = \frac{420}{60} =7 A$

Hence, the current through a conducting wire carrying a charge of 420C  in 60s is 7A
