    Find Equivalent Capacitance Between A & B with Capacitor

    c1 and c2 is parallel meanwhile c3 and c4 are series c3 and c4 will give me 2/3F 2/3F is parallel to C1 and C2 hence C=1+1+2/3=8/3 is that correct?

    How does electric potential relate to point charges in homework problems?

    That mean kq/r+kq/r=0 something like that?

    Calculating Electric Field and Distance for a Point Charge

    Perhaps it should be kqq/r can u explain this concept to me? i thought product of charges over distance is only used to determine the force, never thought u can be express as electric potential too.
