Question

An electric heater of resistence 8ohm takes a current of 5 ampheres. Calculate the heat produced in 30sec.

Answer 1

Heya......!!!!

_____________________________

Given in the question:

= Resistance => 8 Ω
= current. => 5 A
= time => 30 sec

We can take out the Heat produced by applying the formulae :-

=> H = i²Rt

Putting the values we get :

=> 5² × 8 × 30
=> 25 × 8 × 30

Heat produced is = 6000 J
