Question

A charge of 10 mc flows through a wire of cross section 2.5 mm2
normally in 2 seconds. The current is
(A) 4m A
(B) 5m A
(C) 20m A
(D) 25m A​

Answer 1

Answer:

5mA

Step-by-step explanation:

(i= Q/t)

i= 10/2

i=5.

Answer 2

Given: Charge $q=10$

Cross Section$=2.5mm^{2}$

time$=2 sec$

Thus to find the current we have to apply the formula of current,

$i=\frac{q}{t}$

Thus applying the value, we get,

$i=\frac{10}{2}$

Hence we get the value of current as $5mA$.
