Impedance is like as resistance of capacitor and inductor.

What is impedance? please define in simple words.

Amplifier is an electronic device that increases the power of a signal. This occur due to the conversion of energy from a power supply and controlling the output to match the input signal shape but with a larger amplitude. When this is done, then an amplifier can be described as modulator of the output signal of the power supply.

Infinite bandwidth means op-amp work within all range of frequencies, but practically it is not possible.
