Why short circuit calculation is not required for LT cables?
Lt cables has own impedance which reduce the short circuit fault level
Techniques required for increasing the input impedance?
...of what? to a house, to a breaker (to lower fault current level?), to an amplifier circuit?
Why is it necessary to bias a transistor when it is to be used as an amplifier?
Biasing is necessary in a transistor circuit to keep the transistor working. Without proper biasing, the circuit will fail
At a frequency below the resonant frequency parallel circuit is?
A parallel resonant circuit has low impedance, when non resonant; however the impedance rises sharply, as the circuit comes to resonance.
What is transistor relay driver?
a transistor circuit for driving the coil of a magnetic relay.
Why you go for bootstrap circuit?
Bootstrapping is used to allow bias to be applied to the base of a transistor while maintaining a very high input impedance.
What is a driver transistor?
dirver transistor is added in a circuit so as to provide required voltage at an operating current which can not be provided by the microcontroller
Why short circuit calculation is not required for LT cables?
Lt cables has own impedance which reduce the short circuit fault level
Short definition of impedance in connection with ac?
Impedance in an AC circuit is like resistance. In fact, impedance is measured in ohms, just like resistance. Impedance takes into account the fact that current and voltage are often not in phase with each other due to capacitive and inductive reactance.
Impedance of electric circuit?
The impedance of electric circuit refers to the measure of the opposition that a circuit presents to a current when a voltage is applied.

The total opposition to an alternating current presented by a circuit is called a?
impedance
How does capacitor improves the performance of a circuit?
This depends on what kind of circuit you have. Generally, you cannot just add a capacitor to a circuit and 'improve it'. Probably, though, you mean an amplifier, anf by improve, you mean improved frequency response. In a transistor amplifier, you sometimes want increased gain at higher frequencies. By adding a capacitor from the emitter to ground, you create a low impedance path to ground for the AC signal. This lowered emitter impedance increases the gain of the amplifier, for frequencies where the capacitor looks like a low impedance, or high frequencies.
Why short circuit has very low resistancs?
A short circuit is defined: An unintentional connection of low resistance or impedance in a circuit such that excessive and often damaging current flows in it (from Wiktionary.org) Why a short circuit has very low resistance is very simple: because that's how "short circuit" is defined.
At a frequency below the resonant frequency parallel circuit is?
A parallel resonant circuit has low impedance, when non resonant; however the impedance rises sharply, as the circuit comes to resonance.
Resistive forces in an ac circuit is?
Impedance
