Thank You. I was using the wrong equation for the last step

All I know is that resistance is 1/total=1/r1+1/r2+1/r3. I calculated 3.83 ohms

Homework Statement A current I9 = 2 A flows through the 9 ohm resistor. At what rate does the battery deliver energy to the entire circuit? Homework Equations There are 3 resistors in the circuit, all wired in parallel. r1=15 ohms, r2=12 ohms, r3=9 ohms The Attempt at a Solution

Homework Statement A negative charge Q1 = -8 nC is fixed on the x-axis at (x = -4, y = 0). A positive charge Q2 = +8 nC is fixed on the x-axis at (x = 4, y = 0). For the sake of reference, consider point A, at (x = 0, y = 5). All locations are in meters. What is the sign of the...

Follow up questions: What is the potential at x = -5 ? How much work is required to move the +4 nC charge (Q2) from its original location at x = 5 to x = 3 ? Any explanation would help? Thank You

Homework Statement A pair of charges sits on the x-axis, a charge Q1 = +9 nC at the origin and Q2 = +4 nC at x = 5. Assume no other charges are present. All coordinates are in meters. At which one of these points is the net electric field equal to zero? Homework Equations The...
