Consider a wire with resistivity ρ in a circuit. It has length L1 and diameter d1. This wire has to be replaced by a wire of the same material but longer by a factor of 3. With the constraint that the resistance of the new wire has to be the same as the resistance of the original wire, what must the diameter of the new wire be?

Consider the three capacitor arrangements below where C1=[C1]

Of the three scenarios listed below, determine which has the greatest magnitude of current through the source and calculate that value.   A. a [R1]-Ω resistor connected to a 1.5-V battery that has an internal resistance of 0.10 Ω. B. an unknown resistor connected to a 13.0-V battery that has an internal resistance of [r2] Ω and a terminal voltage of 11.0 V. C. a [R3]-Ω resistor connected to a 4.0-V battery that has a terminal voltage of 3.6 V but an unknown internal resistance. Express your answer in units of A and to 2 decimal places. Numerical answer only. Don’t type in the units or use scientific notation.

Consider the charges below arranged on the vertices of an equilateral triangle. What is the direction of the net force on q2 if |q1|=|q2|=|q3|? Question ID: 3778895

Two parallel plate capacitors are shown below. Capacitor on the left has capacitance C = Q/V, area A, and plate separation d. Capacitor on the right has the same capacitance and area. If the voltage is held constant and the plates are separated by a factor d’=2d, what is the new charge on the plates, Q’, after the separation?

Two point charges, q1 = [q1] μC and q2 = [q2] μC, are placed on the corners of a rectangle as shown in the figure, where h = [h] m and w = [w] m. The x component of the electric field due to q2 at the origin O is: Give your answer in units of N/C and round to the nearest whole number. Your answer should be numerical only, don’t type the units. Hint: Components of vectors can be positive or negative. For example, if a vector is pointing in the negative x direction, then the x-component should be negative. No partial credit for missing a negative sign.
