Question

calculate how much charge passes through the LED in 1 hour if the current flowing in the circuit below is 350mA

Answer 1

Given the the current flowing in the circuit and the elapsed time, the charge that passes through the LED is 1260 Coulombs.

What is Current?

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;

I = Q/t

Where Q is the charge and t is time elapsed.

Given the data in the question;

• Time elapsed t = 1hr = 3600s

• Current I = 350mA = 0.35A

• Charge Q = ?

We substitute our given values into the expression above to determine the charge.

I = Q/t

Q = I × t

Q = 0.35A × 3600s

Q = 1260C

Therefore,  given the the current flowing in the circuit and the elapsed time, the charge that passes through the LED is 1260 Coulombs.
