Question

Answer true or false to each of the following statements.

The angle of phasor represents its magnitude.
The ratio of the primary voltage to the secondary voltage of a transformer is equals the ratio of the turns in the secondary coil to primary coil.
In an ideal transformer the magnetic flux in the primary coil equals the magnetic flux in the secondary coil.
The current in a resistor is in phase with the voltage across the resistor.
An inductor and a capacitor in series will only resonate when the right value of resistance is in series with them.

Explanation / Answer

The angle of phasor represents its direction but not it's magnitude.hennce the given statement is false

principle of transformer is Vp/Vs = Np/Ns,but given that Vp/vs = Ns/Np

so the given statement is false

transformer works on the principle of mutual inductance

so the given statement In an ideal transformer the magnetic flux in the primary coil equals the magnetic flux in the secondary coil. is true

in case of resistor the voltage and current are in phase
so the given statement is TRUE

resonance condition is f = 1/(2*pi*sqrt(L*C))

so only for one right value of resistance the circuit is in resonance

so the given statement is TRUE
