5. A 25.0 cm long solenoid has a radius of 3.00 cm and has 2000 turns of wire. The current in the solenoid varies according to the function I (t) = 6t - 8t2, where I is in amperes and t is in seconds; the direction of the current in the solenoid is shown below (clockwise as seen from the left). A copper ring of radius 5.00 cm and resistance 0.200 is placed around the solenoid. What is the magnitude and direction (specify clockwise or counterclockwise) of the current in the copper ring at t = 0.500 s? Isol
A 140 V emf is across a transformer's 190-turn primary coil. How many turns should the secondary have in order to produce a 40 V emf, expressed as an integer. Can you set up Es/Ep = Ns/Np. I know I am to solve for Ns. I need to see what is given tied to the symbols, then I see what to what better.
