New Concepts/Shortcuts 8 Flashcards
torque on an electric dipole
potential energy of an electric dipole
energy stored in a capacitor
force between the capacitors
electric field due to a dipole at an point
effect of inserting dielectric in capacitor
at constant V
effect of inserting dielectric in a charged capacitor
what can be thought if we want an area of quad made by the intersecting of circle’s radius
we can check if the circles are orthogonal
whats the line of thinking for a question with common tangents condition
write the standard equation and then compare the equations
time constant for charging a capacitor
drift velocity formula
how do be approach these kinda q
first find the charge in a sphere in r distance
and then sub it in electric field formula
formula for finding charge in a particular distance r in a variable charge density
