ElectroMagnetic InductionHard
Question
The magnetic flux through a stationary loop with resistance R varies during interval of time T as φ = at (T - t). The heat generated during this time neglecting the inductance of loop will be
Options
A.
B.
C.
D.
Solution
φ = at(T - t) ⇒ 
= aT - 2at
⇒ i =
= (aT - 2at)
Heat =
(aT - 2at)2 Rdt
=
= Heat
Heat = 
= aT - 2at⇒ i =
= (aT - 2at)Heat =
(aT - 2at)2 Rdt=
= Heat
Heat = Create a free account to view solution
