Question
Describe the method of charging a conductor by induction.
Advertisements
Solution 1
INDUCTION: “Charging an uncharged conductor by bringing a charged conductor near it without touching is called INDUCTION

Place uncharged conductor B near positively charged conductor A nearer end of B has negatively charged electrons attracted towards positively protons remain on the farther end of B.
Hence, nearer end of B is charged oppositely i.e. negative. We can test it by pith ball electroscope. On removing charged body A away from B, The body B becomes neutral due to protons and electron in B are equal and have opposite charge.
Solution 2
When charging a conductor by induction, a charged object is brought close to but does not touch the conductor. In the end, the conductor has charge of the opposite sign as the charge on the object.
One way to carry out the four-step process:
- Bring the charged object close to, but not touching, the conductor. Charge on the conductor shifts in response to the nearby charged object.
- Connect the conductor to ground. The ground is basically a charge reservoir - anything that can give up or receive charge without noticing the change. Electrons flow from ground to the conductor if the charged object is positive, and the opposite way if the object is negative. The conductor now has a net charge with a sign opposite to the sign on the charged object.
- Remove the ground connection. The transferred electrons can't get back to where they came from.
- Remove the charged object. The net charge distributes itself over the surface of the conductor.
