Homework Statement In the circuit above, use R1 = 4Ω, R2 = 3Ω, V0 = 10V, and k = 1/5 Find the value of ix Find the power delivered by the dependent source 2. The attempt at a solution So what I assumed was that Ix+kIa=Ia so k=1/5 so Ix=(4/5)Ia then the equation for Ix would be Ix +...

Thanks! I knew it was probably pretty simple, but I was just unsure of what to exactly do. thanks

Homework Statement Three point charges +Q are placed at three corners of a square, and a charge -Q is placed at the fourth corner. If Q = 1.00 milli-coulomb and the side of the square has length 1.00 m, find the magnitude of net force that the positive charges exert on the negative charge...

Homework Statement A photocopier imaging drum is positively charged to attract negatively charged toner particles. Near the surface of the imaging drum, the E field has a magnitude of 1.90 × 105 N/C A. What must be the be the magnitude of the negative charge on a toner particle of mass 2.80 ×...
