5) A solenoid with 2 x 106 turns per meter runs through the x-y plane. It initially has a current of 7 amps running clockwise. A wire shaped like a equilateral triangle would 10 times with sides of length 2 meters is placed in the x-y plane in the solenoid. Over a a time of 0.7 seconds, the solenoid changes its current somehow which induces a (average) current in the triangle of 16 amps running counter-clockwise. If the resistance of...

ri R$ 7:) Here, each V represents a change in voltage (in volts) at a battery, each R represents a resistance (in ohms) at a resistor and each I represents a current (in amps) through a wire. These quantities obey two simple laws: 1. Ohm's law: The voltage drop across a resistor is V = IR. 2. Kirchhoff's second law: The sum of all the voltage changes in a closed loop is zero. Using these two laws, we can construct...

Learning Goal: To use the mesh-current method to analyze circuits containing resistors and independent voltage sources. The mesh-current method is a general technique for solving circuits. Fundamentally, it involves writing KVL equations around all meshes in a circuit. You should review KVL and the definition of a mesh before beginning. In this tutorial, you will use the mesh- current method to find the current through the 1 k2 resistor, io, and the voltage drop across the 5 k22 resistor, vo,...
