Homework Statement
Two flat charged plates create a uniform electric field (E). What happens to voltage (V) when the distance (d) is doubled?
Homework Equations
Voltage in uniform electric field:
V = E*d
Capacitance equations:
V = Q/C
C = K * A/d
The Attempt at a Solution
The simple thing to do would be that since d is increased by 2, and V = Ed, then V goes up by 2.
But that does't make sense...if you keep moving the plates apart would you keep getting an increase in voltage?
I think we need to incorporate the change in capacitance somehow...
