Question

Answer true or false to each of the following statements.

1. The angle of phasor represents its magnitude.

2. The voltage across an ideal capacitor lags the current by 90 degrees.

3. In an ideal transformer the current in the primary coil always equals the current available from the secondary coil.

4. An inductor and capacitor in series will oscillate at any frequency.

5. The ratio of the primary coil turns to the secondary coil turns of a transformer is equal to the ratio of the primary voltage to the secondary voltage.

Explanation / Answer

here,

Answer true or false to each of the following statements.
1. The angle of phasor represents its magnitude.
False , the angle of phasor is independent of the magnitude of the phasor

2. The voltage across an ideal capacitor lags the current by 90 degrees.

True , for a capacitor , current will lead the voltage by 90 degree.

3. In an ideal transformer the current in the primary coil always equals the current available from the secondary coil.

False , for an ideal transformer , power in primary is always equal to power in secondary.

4. An inductor and capacitor in series will oscillate at any frequency.

False, inductor and capacitor will oscillate at the resonance frequency.

5. The ratio of the primary coil turns to the secondary coil turns of a transformer is equal to the ratio of the primary voltage to the secondary voltage.

Ture , as the voltage ratio is

Vp/Vs = Np/Ns
