Question

5 ut during a 3 minute period if the voltage drop across the element is 950 V and the charge passing through the element is a 400C?

Answer 1

soli- Given voltage drop, V = 9.500 chaoge, a Hooc time, t = 3 min 2 - 3 x Gosec t-180 sec. u know, dissipated, energy €=v2 Joules. e it cusent i=9 - 400 = 2.222A t 180 v=iR FOR=v 9.50 2.222 R=4,2752 HE= (9.50) x 180 X 180 4 275 E= 3800J-3-8kJ .. Energy dissipated = 3.8 kJ /
