Question

and
08-2 write ten sentences (adjective of quality
Jadjective of quantity).​

Answer 1

Answer:

(R) = 20 Ω

(I)= 5 A

(t)= 30 s

Now we know that H= I2Rt

use it here = 5×5×20×30

= 15000J=1.5×104J

The heat developed in 30s is 1.5×104J

Answer 2

Answer:

(R)=20

(I)=5 A

(t)=30 s

Now we know that H=12Rt

if it is wrong I am sorry. ..
