Class 12PhysicsMoving Charges and MagnetismThe Moving Coil Galvanometer (Sensitivity) and Ammeter and Voltmeter Conversion
Medium$A$ galvanometer having a coil resistance of $30\,\Omega$ shows full-scale deflection when a current of $2\,A$ passes through it. It can be converted into an ammeter to read currents up to $10\,A$ by:
- Aby putting in series a resistance of $240\,\Omega$
- Bby putting in parallel a resistance of $240\,\Omega$
- Cby putting in series a resistance of $7.5\,\Omega$
- Dby putting in parallel a resistance of $7.5\,\Omega$
