A current of 5. 0 amperes is passing through a piece of wire. Determine how long it takes for 30 coulombs of charge to pass thro
1 answer:
The time taken for the charge to pass through the cross-section of the wire is 6.0s.
Given the data in the question;
Current;
Charge;
Time;
Current is simply the rate of flow of charged particles i.e electrons caused by EMF or voltage.
If a charge passes through the cross-section of a conductor in a given time, the current I is expressed as;
Where Q is the charge and t is time elapsed.
We substitute our given values into the expression above to determine the time it took the charge to pass through this wire.
Therefore, the time taken for the charge to pass through the cross-section of the wire is 6.0s.

Answer:
The magnetic field strength due to current flowing in the wire is9.322 x 10⁻⁶ T.
Explanation:
Given;
electric current, I = 21.3 A
distance of the magnetic field from the wire, R = 45.7 cm = 0.457 m
The strength of the resulting magnetic field at the given distance is calculated as;
Where;
μ₀ is permeability of free space = 4π x 10⁻⁷ T.m/A
Therefore, the magnetic field strength due to current flowing in the wire is 9.322 x 10⁻⁶ T.
