Practise IB Physics HL D.2.5 by analysing induction, grounding, contact and electron-flow charge-transfer processes.
A conducting sphere has radius 48 cm . The electric potential on the surface of the sphere is 3.4×105 V.
The sphere is connected by a long conducting wire to a second conducting sphere of radius 24 cm . The second sphere is initially uncharged.

Describe, in terms of electron flow, how the smaller sphere becomes charged.
electrons leave the small sphere «making it positively charged»
