Effective resistance = 40+60=100 ohm

Potential difference = 220v

H = (V/R )²Rt= (220/100)² x 30x 100

= 4.84 x 30x100

= 14520J


susain2001: That is for power. The question asks heat in 30 sec.
KunalMitra: thank you
susain2001: You are wrong. Sorry.
susain2001: Please edit the answer before they report.
