A cylindrical solenoid 49 cm long with a radius of 7 mm has 325 tightly-wound turns of wire uniformly distributed along its length (see the figure). Around the middle of the solenoid is a two-turn rectangular loop 3 cm by 2 cm made of resistive wire having a resistance of 135 ohms. One microsecond after connecting the loose wire to the battery to form a series circuit with the battery and a 20 resistor, what is the magnitude of the current in the rectangular loop and its direction (clockwise or counter-clockwise in the diagram)? (The battery has an emf of 9 V.)
a rod of semiconducting meterial of length L = 2 m and cross-sectioanal area A=5mm2 lies along the x axis between x=0 and x=L. the meterial obeys Ohm's law, and its resistivity varies along the rod according to p=p0 (1-(x2/L2)) where p0=4,5 * 10-4 ohm*m. the end of the rod at x=0 is at a potential V0= 30 V greater than the end at x = L. a)what is the total resistance, in units of ohm, of the rod ? b)what is the current, in units of miliamperes in the rod? c)what is the electric potential, in units of Volt in the rod at x=L/2 ? d)what is the electric field magnitude E, in units of V/m, in the rod at x=L/2 ?

Consider the circuit below. Point b is grounded(potential=0). Determine the potential at a. Two resistors of cylindrical shape, A & B, made from the same material. The length of resistor A is twice that of resistor B. The diameter of B is half that of A. Determine the ratio of Resistance of A/Resistance of B.
An electric toothbrush has a base designed to hold the toothbrush handle when not in use. As shown, the handle has a cylindrical hole that fits loosely over a matching cylinder on the base. When the handle is placed on the base, a changing current in a solenoid inside the base cylinder induces a current in a coil inside the handle. This induced current charges the battery in the handle. We can model the base as a solenoid of length ℓ with NB turns (as shown), carrying a current i, and having a cross-sectional area A. The handle coil contains NH turns and completely surrounds the base coil. Find the mutual inductance of the system.
I need helpo with this. I need step by step solutions for this and I cant figure it out. Wire to be used in buildings and homes in the United States is standardized according to the AWGsystem (American Wire Gauge). Wires are assigned a gauge number according to their diameter.The scale ranges from gauge 0000 to gauge 36 in 39 steps. The equation for the wire gauge interms of the wire diameter in millimeters is the picture. (a) What is the equation for the diameter in millimeters in terms of the wire gauge N?(b) You have two wires, one that has five times the diameter of the other. By how much do thewire gauges differ for the two wires? (Give your answer to the nearest integer.)
