Answer:
A voltmeter is designed to have a high resistance and should be connected in parallel in order to measure accurately. By this, no current will flow through the voltmeter i.e. it won't disrupt the current that should flowacross a resistor or load.
The connecting of voltmeter in series is equivalent to connecting a very high resistance in series with the circuit. By this only small insignificant amount of current flow through the circuit and nearly results in an open circuit.
