Why voltmeter is always connected in parallel with the load resistance?
1 Answer
A voltmeter is a high resistance device and measures potential difference across two points of an electrical device. When it is connected in parallel across any component of a circuit, it draws a very small current from the main circuit, and the voltage does not change in parallel combination such that it can measure the voltage accurately. If it is connected to series, voltage is divided and hence voltmeter cannot measure potential difference accurately.
