Question

if a twelve ohm nicrome resistance ,coil is added to 12volt battery and current flows 30 minutes then the calculate the amount of heat produce ?​

Answer 1

Explanation:

given Rs equals to 12 ohms,voltage is equals to 12 volts and time is equals to 30 minutes

so ,

H=(v^2/,r)t

H=12×12×30/12

H=12×30=360J
