What is input impedance of amplifier?

Basically, measure the input voltage and current, output voltage and current, and apply Ohm's Law.

Practically, you can apply a signal to an amplifier and measure its output. Then place a variable series resistor between the signal generator and adjust the resistor until the output drops to 50%. The resistor's value is the amp's input impedance, Zin.

While this will work OK at DC and audio frequencies, once you get to some hundreds of kilohertz and higher, you will need specialist equipment to measure Zin.

You might expect that you can put a variable resistor on the output and adjust the resistor until you get 50% of output. This will work with low-power amplifiers with substantial Zout.

Most audio amplifiers have *very low* Zout (less than an ohm), so trying this will probably blow the amplifier. You will need special test gear for (i) audio power amplifiers, even those in portable equipment, and (ii) anything above a few hundred kilohertz, as for Zin.

What is the best test series for IIT JEE advance Resonance Bansal Allen Narayana or FIITJEE?

According to me. CatalyseR's JEE Shikhar online JEE test series was very good at my time but really after solving paper, it was like . chal yaar bahot Kuch sikhaya paper ne. this kind of feeling was awesome. Don't always try to join all the test series and waste your time . just mug up chemistry in leisure time . and solve question properly one or 2 times. It's enough.
