Homework Statement
(The information is for several questions and i have posted one of them)
Two coils magnetically coupled, Voltage of 240v, 50Hz applied to coil 1, current of 2A flows, second coil connected only to a high impedance rms voltmeter reading 100v
find: The peak total flux linkage with coil 1
Homework Equations
e = d{lamdar}/dt
The Attempt at a Solution
ok re-arranging the equation to find {lamdar} which is the flux linkage in coil 1
{lamdar}=et
e = 240 (as given)
t = 1/f (and as radial 2 x pi x f) so t = 1/(2 x pi x f)
t = 2.18... x10-3
so {lamdar}= 0.7639 Wb-turns
but the answer given say should be 1.079Wb-turns
please help will be very gratefull have been at this for hours now.
