Q1:

An oscilloscope has an input impedance consisting of 1 MΩ and 20 pF is parallel. A high impedance probe connected to input of this oscilloscope has a 10 MΩ series resistance. This 10 MΩ series resistance

A may not be shunted

B should be shunted by 2 pF capacitor

C should be shunted by 20 pF capacitor

D should be shunted by 200 pF capacitor

ANS:B - should be shunted by 2 pF capacitor

Source and load impedance are complex conjugate. Maximum power transfer.
