To measure potential difference across a resistor, voltmeter is always connected in:
Correct answer: A. Parallel
- A. Parallel
- B. Series
- C. Some times in series and some times in parallel
- D. None of the above
Explanation
When measuring potential difference (voltage) across a component like a resistor, the voltmeter is connected in parallel with the component. This is because the potential difference across a component is the same regardless of how the component is connected in the circuit. Connecting the voltmeter in parallel allows it to measure the voltage across the resistor without affecting the current flowing through it.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
