Answer:
Explanation:
The concept of amperes law is applied;
Given the current density vector in the medium is J,
the electric flux density vector is D,
and the magnetic flux density vector is B. The line integral of the magnetic field intensity H
considering the orientation of the contour is adopted according to ampere law;
deta x B = Jc + JD
delta x B = Jc + partial differential D/partial differential t
where Jc = conduction current density
JD = displacement current density
Answer:
The S. I unit of current is Amphere
Answer: True
Explanation: The amount of natural gas supplied in the residential area has lesser cost as compared with the electric power industry. The cost is lesser for the natural gas because it is abundantly available resource in the environment and electricity is generated by several methods and thus supplied so there is more effort and resources required and this costs more .Therefore, natural gas is cheaper as compared with electric power .
Answer:
(a)The mass flow rate =
2.297×10^6 lb/HR
(b)the rate of heat transfer =2700.847×10^6Btu/hr
(c)thermal efficiency is 37.025%
