. in the gure below, rectangular circular wire has length a = 2.2 cm and width b = 0.8 cm, and resistance R = 0.4 gw. This rectangular wire is placed near straight wire of innite length carrying with current i = 4.7 A. This rectangular wire then moved away from the straight wire at constant speed of v = 3.2 Innifs. The center of the rectangular wire is at distance r = 1.5b. What is the induced current in the rectangular wire, and which direction? . In the picture below, there are two long wires carrying currents i1 and i2, where i1 is 0.03 A and i2 is 0.04 A. The distance between the two wires 'oni 0 is a and b where a = b. As a result of these two currentcarrying wires, a magnetic eld B appears at point 0. What value of current i1 must be changed to rotate B by 20 clockwise 3. In the Figure below, the ideal battery has emfs= C531:150 V and 2 = 50 V and the resistance is R1 = 3.0 Q and R2 = 2.0 Q. If the potential P is 100 V, how much at Q? 4. The picture on below shows the electric potential of a copper wire that carries current from a high potential Vs = lZuV While X = 0 to the zero potential point on 3;: 3n]. calculate the current on the wire?
