Understanding the Galvanometer and Voltmeter Conversion
A galvanometer is an instrument used to detect and measure small electric currents. However, to measure voltage, a galvanometer needs to be converted into a voltmeter.
Why High Resistance in Series?
- Functionality: When a galvanometer is converted into a voltmeter, it measures the potential difference (voltage) across two points in a circuit.
- Current Limitation: A galvanometer is designed for low currents. By connecting a high resistance in series with the galvanometer, we limit the current flowing through it when measuring higher voltages.
- Voltage Measurement: The high resistance allows the galvanometer to measure the voltage without drawing significant current from the circuit. This ensures that the measurement is accurate and does not affect the circuit's operation.
Effects of Other Connections
- High Resistance in Parallel: This would short-circuit the galvanometer, potentially damaging it and providing inaccurate readings.
- Low Resistance in Series: This configuration would allow too much current to flow through the galvanometer, risking damage and incorrect readings.
- Low Resistance in Parallel: Similar to the high resistance in parallel, this would bypass the galvanometer, leading to inaccurate measurements.
Conclusion
In conclusion, to convert a galvanometer into a voltmeter effectively, one must connect a high resistance in series. This configuration ensures accurate voltage measurement while protecting the instrument from high currents.
