Answer 2

$\sf\huge\bold{Answer:}$

Given :

Charge (Q) = 420 C

Time(t) = 5 minutes

To find :

Current flowing through wire

Solution :

Charge (Q) = 420 C

Time(t) = 5 minutes

Time in seconds

1min = 60seconds

5min = 5×60 seconds = 300 seconds

$\fbox{Formula used : }$

$\sf\purple{:⟶current(I) = \frac{charge(Q)}{time(t)} }$

$\sf:⟶I = \frac{420 C}{300 s}$

$\sf{:⟶I = }$$\displaystyle{\sf { \cancel{ \frac{420}{300} }}}$

$\sf:⟶I = 1.4 C/s \:or\: A$

SI unit of Current is ampere ( A )

$\sf\huge\purple{I = 1.4 A}$
