Can you measure contact potential with a normal multimeter? Why not?
Homework Answers
No, We cannot. The potential barrier is across the Junction,
typically creating a "barrier" for the free electrons to move from
n- side to the p side.
the potential is not from the ends . And it is the
moment there are metal contacts joined to the p side and n side,
The potential is "neutralised". that is the p-n junction is not a
battery to provide a voltage across a voltmeter.

You have a new Digital Multimeter and would like to know its input impedance. You have three different pairs of resistors with values of 600, 60k and 6M. You construct a voltage divider from each pair, power it with 20V DC and use the new meter to measure the output voltage. For R=600, you measure 10V. For R=60k, you measure 9.95V. For R=6M, you measure 6.66V. What is the input impedance of your new meter?
