Question

A particular point on a wire has a constant 250 mA250mA of current flowing through it. How much charge has passed through that point in the wire in 4 seconds? Select all possible correct answers.


a.62.5C


b.100mC


c.1C


d.250mC

Answer 1

Answer:

Sorry i don't know the answer

Answer 2

The charge passed through that point in the wire in 4 seconds is 1 C

option c is correct

1. Current is the rate of flow of charge or how much charge is passing thorough per unit time
2. the relation between current ,charge and time is given as
3. Q=It
4. here Q is charge S.I unit of charge is Coulomb
5. I is current flowing,S.I unit of current is Ampere =1000 milliampere.
6. t is time taken in seconds  
7. The charge passed through that point in the wire in 4 seconds is
8. Q= 0.250 X 4 = 1 C
