So four goes five times, so that'll be five joules per coulomb, and joules per coulomb 0000005866 00000 n The external force required points in the opposite direction, For our specific example near a point charge, the electric field surrounding, To deal with the problem of the force changing at every point, we write an expression for the tiny bit of work needed to move, To figure out the total work for the trip from. xref Direct link to Pixiedust9505's post Voltage difference or pot, Posted 5 months ago.
