Question

An electric current of 104.0 mA transports 1.00 kC of charge.

Calculate the time this took. Be sure your answer has the correct unit symbol and the correct number of significant digits.

Answer 1

Answer:

26.71 hours

Explanation:

Current, i = 104 mA = 0.104 A

charge, q = 1 kC = 1000 C

The definition is current is

The amount of charge passing through a conductor in 1 second is called electric current.

i = q / t

t = q / i

t = 1000 / 0.104 = 9615.38 seconds

t = 26.71 hours.

Answer 2

Answer:

The time would be 9.62 x $10^{3}$ s

Explanation:

The electric charge that is experienced by a body is the product of current and the time, it is expressed as;

Q= I x t ....................1

where Q is the charge = 1.00 KC  x 1000 = 1000 C

I is the current = 104.0 m A x = 0.1040 A

To obtain the time we make t the subject formula in equation 1;

t = Q/I..................2

Substituting the values into equation 2 we have

t =  1000 C / 0.1040 A

t = 1000 A per s / 0.104 A

t = 9615.3846 s

t = 9.62 x s

Therefore the time would be 9.62 x s
