(Be clear and concise. Typing work is strongly suggested. Will thumps up depending on the quality of work done.) (Please answer Q1a, b, and c) Find the impedance of a 60.0-Hz circuit with a 2.1- ohm resistor connected in with a 108.0-mu F capacitor. A magnetic field increases from 0 to 0.09 T in 2.1 s. How many turns of wire are needed in a circular coil 12 cm in diameter to produce an induced emf of 4.6 V? A wire with a length of 2.5 m and a mass of 0.75 kg is in a region of space with a magnetic field of 0.80 T. What is the minimum current needed to levitate the wire?Explanation / Answer
Z = [R2 +(1/C)2] where =2f
= [2.12 +(1/(2*60.0*108.0 x 10-6)2]
= 24.65
Please post b and c in individual questions
