3. OHMS PER VOLT RATING

4. Loading effect A voltmeter when connected across two points in a highly resistive circuit, acts as a shunt for that portion of the circuit and thus reduces the equivalent resistance in that portion of the circuit. The meter will then give a lower indication of the voltage drop than actually existed before the meter was connected. This effect is called as loading effect.

5. To avoid loading effect use high sensitivity voltmeter. Refer class notes for problems
