What is Ampere's circuital law and how can it be proved?
Ampere's circuital law states that the magnetic field around a closed loop is equal to the sum of the currents passing through the loop. It can be proved using the concept of magnetic flux and applying the law to different current-carrying geometries.
Define and explain the concept of a solenoid.
Define and explain the concept of a solenoid.
A solenoid is a coil of wire wound in a helical shape. When current flows through it, it produces a magnetic field. It can be used to create a uniform magnetic field inside the coil.
How can you convert a galvanometer into an ammeter and voltmeter?
How can you convert a galvanometer into an ammeter and voltmeter?
To convert a galvanometer into an ammeter, a low resistance shunt is connected in parallel to the galvanometer. To convert it into a voltmeter, a high resistance is connected in series with the galvanometer.
