(e)
The value that gets changed if a dielectric is inserted
(e)
Answer to Problem 49P
The following things will changes when a dielectric is inserted.
- Capacitance
- Charge
- Energy
Explanation of Solution
When a dielectric is inserted, the capacitance will changed, so the charge and energy will also get changed. But electric field did not changed as it is only depends on the battery voltage and the plate separation.
Conclusion: Capacitance, Charge and Energy will be changed when a dielectric is inserted.
