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.
Although an ideal voltmeter has an infinite internal resistance, this theoretical ideal is usually not met in practice.

3. The circuit is as shown below. Assuming that the ammeter and voltmeter are ideal, means they don't affect the current in the circuit, so an ideal voltmeter has a very high resistance while an ideal ammeter has a negligible resistance.

Exercise 2. An instrument used to measure current is called an ammeter. The ammeter is connected into a circuit in series in the loop in which the desired current reading is required. The resistance of an ideal ammeter is zero, and it is essential in real ammeters that the resistance of the instrument be very small compared to other resistances in the circuit. Why? R2 Ri a)-A meter to measure potential difference is called a voltmeter. To find the potential...
