Question

4. If the current is flowing through a 10 ohm resis-
tor, then in which one of the following cases maxi-
mum heat will be generated ? Heat =I?R
(a) 5 A in 2 minutes (b) 4 A in 3 minutes
(c) 3 A in 6 minutes (d) 2 A in 12 minutes​

Answer 1

Answer:

✅Here's your answer

Given,

R = 10 Ohm , I= 5A , T=2 minute = 200sec

(a) H = I^2 RT

✔= 25×10×200

✔= 50000 J

(b)

H = 16×10×300

✔= 48000 J

(c) H=I^2 RT

✔= 9×10×600

✔= 54000J

(d) H=I^2RT

✔=4×10×1200

✔=48000 J.
