Question

ICS
एक 5Amp की धारा 10 ओम के प्रतिरोध में 4 मिनट तक बहती है,
तो इस समय में, किसी भी अनुप्रस्थ काट में से कितने कूलाम गुजरते
(1) 12 coulombs
(2) 120 coulombs
(3) 1200 coulombs
(4) 12000 coulombs
P​

Answer 1

Charge flowing will be equal to 1200 C

So option (3) will be correct answer

Explanation:

We have given current i = 5 amp

Resistance R = 10 ohm

Time t = 4 minutes

We know that 1 minute = 60 sec

So 4 minute = 4×60 = 240 sec

We have to find the charge flowing through the cross section

Charge will be equal to $charge=current \times time=5\times 240=1200C$

So option (3) will be correct answer
