Given information

  • We have a circuit diagram with an ammeter(A) and a voltmeter(V) connected across the resistor R.
  • Resistance of the voltmeter is .

Step-by-step explanation

Step 1.

Points to remember.

  • A voltmeter is a device that measures voltage or potential difference hence its internal resistance is very high and ideally infinite. It is connected parallel to the device.
  • An ammeter is a device that measures current hence its internal resistance is very low or ideally 0 ohms. Shunt resistors are used in ammeters to measure the voltage drop across hence current through the circuit. It is connected in series with the device.
