26.
Which one is correct option?
- A pure capacitor never dissipates energy, but only stores.
- Capacitor can store finite amount of energy even cunent is zero.
- The current through a capacitor is zero if voltage across it d.c.
- Voltage across a capacitor cannot change instantaneously since it would require an infinite current.
- qc(0-) = qc(0+)

If a driving point function N(s) = p(s)/q(s), then
28.
For a half wave rectified voltage, the form factor and peak factor respectively are
29.
A series LCR circuit consisting of R = 20 Ω, | XL | = 20 Ω and | XC | = 20 Ω, connected across an A.C. supply of 200 V rms. The rms voltage across the capacitor is
30.
Assertion (A): In KVL equations involving mutually coupled circuits the sign of M terms can be positive or negative.
Reason (R): Dot convention helps in determining sign of M terms in KVL equations.
