voltage difference is applied a long a wire on the x axis, as shown. A positive charge q1 = +2.0 μC moves from left-to-right and a negative charge  q2 = –2.0 μC moves from right-to-left across the dashed line, in a time interval t = 1.0 s. The total electric current moving across the dashed line is:

Two parallel plates with an area of 3.0 cm2 are separated by a 2.5 mm thick dielectric with a constant of 4.70. If the potential difference between the plates is 120 V and the conduction current ic is 6.00 mA a) what is the charge (q) on each plate?

The electric field in three different wires (I, II, III) made of the same metal, with current flowing in the wires, is shown below. (The rest of the circuit, including the battery, is not shown.) The electric field in each wire is: É 1 = É 3 = (0.050, 0, 0) V/m and É 2 = (0.800, 0, 0) V/m. Wires I and III have a diameter d1 = 0.005 m, and Wire |l has a diameter d = 1.25 × 10¬3 m. In Wire I, 6.19 х 1018 electrons flow per second at an average drift speed 3.5 x 10-º m/s. di d2 dị A В C x=0 x=0.5 m x=0.6 m x=1.6 m I II III

The capacitor in the circuit shown below is initially uncharged. The switch is closed at t = 0 s. AV battery = 30 V, C = 3.0 F, and R = 2.0 2. At sometime after the switch is closed, the current in the circuit is measured to be 9.3 A. What is the charge on the capacitor at this time, in Coulomb? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

Each of the eight conductors in the figure carries 3.15 A of current into or out of the page. Two paths are indicated for the line integral B. ds. What is the value of the integral for (a) path 1 and (b) path 2?
