9. A circuit contains a 1200-1, a 2200-2, and a 3300-9 resistor connected in parallel. The circuit has a total current flow of 0.25 A. How much current
flows through each of the resistors?

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.
