Find the potential at the origin due to the circular arc of charge Q1 = 3.75 nC (where nC = 10−9 C) and the two point charges Q2 = 5Q1 and Q3 = −6Q1 as shown in the figure. The arc's center of curvature is at the origin and its radius is R = 15 m the angle indicated is θ = 20∘.
In the loaded Zener regulator circuit below, RS = 412.1 Ω, and RL = 5.5 kΩ. The Zener diode parameters are VZ = 6.8 V and RZ = 10 Ω. If ⋁S = 15.6 V, what is the Zener current, Iz? Enter your answer in mA.
In the above circuit, the mesh current equation for the mesh d (where the mesh current id is defined) is −250ib + 650id − 400ie + 50iΔ = 0 −250ib + 650id − 400ie − 50iΔ = 0 −250ib + 250id − 400ie − 50iΔ = 0 −250ic + 250id − 400ie − 50iΔ = 0
