Assertion (A): In an op-amp the voltage gain and band width can be adjusted as per requirement

Reason (R): Large value capacitor can also be fabricated on a chip

1. It has low saturation current.
2. It has high value of cut in voltage.
3. It can withstand large reverse voltage.
4. When compared with germanium diode, silicon diode shows a lower degree of temperature dependence under reverse conditions.

1. A pure capacitor never dissipates energy, but only stores.
2. Capacitor can store finite amount of energy even cunent is zero.
3. The current through a capacitor is zero if voltage across it d.c.
4. Voltage across a capacitor cannot change instantaneously since it would require an infinite current.
5. q_c(0^-) = q_c(0⁺)

Assertion (A): Thevenin's theorem and Norton's theorem are dual of each other.

Reason (R): Voltage source can be converted into current source and vice versa.
