Question

An electric charge of 5C passes through a resistor during a pulse of current lasting 10ms.The average current during the pulse is?​

Answer 1

Answer:

We know that Q = ne

Where ’n’ is number of electrons and ‘e’ is charge possessd by One electron.

Here we are given that n = 50×10^17

E = 1.6×10^-19

On appyling the formula - Q=ne

We get Q = 50 × 10^17 × 1.6 × 10^-19

=> Q = 50 ×10^17 × 1.6 / 10^19 (i removed the negative sign in the exponent by bringing it to the denominator)

Q = 50× 1.6 / 10^2

Q = 80/100

Q = 0.8 C

We know that I =Q÷T

I = 0.8 C÷ 125

you can do the maths and

I = 0.0064 A

I think thats the appropriate method and answer
