I got some serious problems with the answers provided to the following questions-
1. A: The current in RLC circuit driven by a sinusoidal voltage may lead,lag or be in phase with the applied voltage.
R: Series resonance does not imply unity power factor condition
A is true and R is false according to me because at resonance power factor is unity in a series RLC circuit.
The answer given is both true & R not the correct explanation.
2. The earths magnetic field always has a vertical component except at the-
My answer magnetic equator and answer given is geographic north pole
