1. What is the Deflection in Galvanometer?

The deflection in a galvanometer refers to the angular displacement of the pointer from its zero position when a voltage is applied across the galvanometer terminals. It is directly proportional to the voltage applied and the sensitivity of the instrument.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \theta_d = V \times S_v \]

Where:

\( \theta_d \) — Deflection Angle (Radian)
\( V \) — Voltage across Galvanometer (Volt)
\( S_v \) — Voltage Sensitivity

Explanation: The deflection angle is calculated by multiplying the voltage applied across the galvanometer by its voltage sensitivity factor.

3. Importance of Deflection Angle Calculation

Details: Accurate deflection angle calculation is crucial for measuring electrical quantities, calibrating instruments, and ensuring precise measurements in electrical experiments and applications.

4. Using the Calculator

Tips: Enter voltage across galvanometer in volts and voltage sensitivity value. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is voltage sensitivity in a galvanometer?
A: Voltage sensitivity is defined as the deflection produced in the galvanometer when a unit voltage is applied across its two terminals.

Q2: What are typical units for deflection angle?
A: Deflection angle is typically measured in radians or degrees, though radians are more commonly used in scientific calculations.

Q3: How does temperature affect galvanometer deflection?
A: Temperature changes can affect the spring constant and magnetic properties, potentially altering the deflection characteristics of the galvanometer.

Q4: Can this formula be used for AC voltages?
A: This formula is primarily for DC voltages. For AC measurements, additional factors like frequency response need to be considered.

Q5: What is the typical range of voltage sensitivity?
A: Voltage sensitivity varies widely depending on the galvanometer design, but typically ranges from 0.01 to 10 mm/mV or equivalent units.
