Question

Calculate how long it takes for the following charges to pass a point in the circuit:

a) 6.0 C, when the current is 0.5 A
b) 48 C, when the current is 36 mA

​

Answer 1

By the formula of current,

I = Q/t

I × t = Q

Q/I = t

Step-by-step explanation:

A) t = Q / I

t = 6 / 0.5

t = 12 sec

B) t = Q / I

First we,

36mA

36 / 1000

0.036A OR 3.6 × 10¯²

t = 48 / 0.036 OR t = 48 / 3.6 × 10¯²

t = 48 × 10² / 3.6

t = 1333.3sec t = 13.3 × 10²
