Electric Potential Flashcards
Electric Potential between charged plates
V=Ed
Equation for Electric Potential Energy
UE = qV = kq1q2 /r
Work of Electricity
WE = -q(Vf - Vi)
Conservation of Energy in Electricity
KE1 + UE1 = KE2 + UE2
KE1 + qV1 = KE2 + qV2
Max velocity of charge when initial velocity = 0
1/2mvmax^2 = q(Vf-Vi)
Equation for capacitance
C = ε0 * A / d
Energy of a Capacitor
UC = 1/2*QV
Equation for Charge
Q = CV
Electric Potential of point charge
V = k * +-q / abs(r)
Explain electric work
When charge released, will accelerate along electric field, changing electric potential and potential energy. This change in electric potential energy is work.
Which directions do charges go
Negative to positive (when negative released, will go to high potential), current moves the other way
