Question

if a 300 mA current flows through a conductor 2 us then how much charge had passed through​

Answer 1

Answer:

0.3 Coulombs

Explanation:

Since you have not given time I suppose it to be 1 second

Current I = Charge Q / Time T

so,

I=Q/T

Also 1mA =10^-3A

putting values

300×10^-3= Q/1

3×100 × 0.001=Q

3×0.1=Q

so,

Q=0.3 Coulombs

Answer 2

Answer:

Q=0.3 Coulombs

Explanation:

Since you have not given time I suppose it to be 1 second

Current I = Charge Q / Time T

so,

I=Q/T

Also 1mA = 10^-3A

putting values

300x10^-3= Q/1

3x100 x 0.0013Q

3x0.1=Q

so,

Q=0.3 Coulombs
