Question

A circuit consists of two 495-k? resistors in series with an ideal 12.0-V battery.

(a) Calculate the potential drop across one of the resistors.


(b) A voltmeter with internal resistance 22 M? is connected in parallel with one of the two resistors in order to measure the potential drop across the resistor. By what percentage will the voltmeter reading deviate from the value you determined in part (a)? (Hint: The difference is rather small so it is helpful to solve algebraically first to avoid a rounding error.)

Explanation / Answer

Hi! Cramster Terms & Conditions were changed recently (I hope you have read them). Now, experts have to send the answers to askers' inbox after you rate them. That is because of people copying from older threads which have public answers. Hence we can only send the answer after you rate. So please give me a Lifesaver rating and I'll send the solution to your inbox or e-mail. You've got no other option to get the answer, because no one can give you the answer over here. Even you might be banned for rating a user that gave the answer directly on your question. You need not worry as I have the solution ready in my notebook. Hope you rate me :)
