Answer the following questions: In any ac circuit, is the applied instantaneous voltage equal to the algebraic sum of the instantaneous voltages across the series elements of the circuit? Is the same true for rms voltage?

The algebraic sum of potential drops across the various elements in LCR-circuit is not equal to the applied voltage. Why?

In an a.c. circuit, with phase voltage V and current I, the power dissipated is

Answer the following questions: Why does the reverse current show a sudden increase at the critical voltage?

Answer the following questions: Why is the current under reverse bias independent to the applied potential up to a critical voltage?

In an a.c circuit, maximum value of voltage is 423 volt. Its effective voltage is:

The given circuit diagram shows a series LCR circuit connected to a variable frequency 230 V source. How do you explain the observations that the algebraic sum of the voltages across the three elements is greater than the supplied voltages?

Answer the following questions: An applied voltage signal consists of a superposition of a dc voltage and an ac voltage of high frequency. The circuit consists of an inductor and a capacitor in series. Show that the dc signal will appear across C and the ac signal across L.

Instantaneous voltage from an a.c. source is given by E=300 sin 314 t. What is the r.m.s. voltage of the source?
