Although an ideal voltmeter has an infinite
internal resistance, this theoretical ideal is usually not met in
practice. The voltmeter in the Figure has an internal resistance of
7 x 109 Ω and is used to measure the voltage across the
resistor R2 as shown. Attaching this non-ideal voltmeter
decreases the voltage across R2. Calculate the magnitude
of this decrease using an emf of 16 V and R1 =
R2 = 200 kΩ.

Q1. You are given a 12 V DC power supply. You are expected to develop a voltage divider to achieve a voltage of nominal 5V value using a pair of resistors from the E 12 range, with the restrition that you are not expected to draw a current of more than 1 mA from the 12 V DC supply i. Develop a simple circuit showing the possible values for each resistor pair, and the range of the DC output possible...
