values of potentials and resistances to find all currents passing through, and voltage drops across all elements in the circuit. Create a general procedure to solve any circuit DC circuit with any number of resistors. You may use the Structure

5) We usually think of wires as perfect (R=0) conductors, which is not quite accurate. Real wires have resistance, and an effort is made to keep this resistance small- usually less than an ohm. This behavior rarely becomes an issue with low power lab circuits. However, it is a big issue with power distribution systems as you will see in ENGR202. a. Design a uniform cylindrical wire that has a resistance of 25 m2 and uses $1 worth of copper. What are the length and diameter of your wire? Note: You can find the resistivity of copper in your textbook, and you should assume that copper costs $2.69 per pound. b. This wire is cut in half, and the two strands are used to power a toaster from an outlet supplying 1800W at 120V. The toaster can be modeled as a pure resistive load. Draw a simple circuit diagram, including the voltage source, resistors to represent the power cord wires, and the calculated resistance of the toaster. C. How much of the 1800W is absorbed by the power cord itself, not…

A potentiometer consisting of a wire of length L0 has a source of emf, ɛ connected across it. When a standard cell with emf V = 6V, in series with a voltmeter, is connected at one end of the wire and at a distance L = 4 cm along the wire the voltmeter circuit is in balance and the voltmeter reads zero. When the standard cell is replaced by a source of unknown emf the new balance length is found to be 6 cm. What is the unknown emf?       Select one: a. 9 V b. 8 V c. 4 V d. 3 V

please answer both questions with most detail as possible. if you use a formulas and manipulate it, please specify from where you got it from. THANK YOU

After solving for the total resistance, and the applied voltage being a given for the circuit, the next logical step is to .....? so that individual component voltages and currents can be found.

Determine the phasor currents I, and I, in the circuit of Fig. 13.13. j2 2 ele j3 2 100/60° V +. j6 Q 12 -j4 2 Figure 13.13 For Practice Prob. 13.2. Answer: I, = 17.889/86.57° A, I2 = 26.83/86.57° A.

We have a square pyramid in which all eight edges are perfect 1-ohm resistors. Find the equivalent resistance between any two vertices.

can someone show me how to do this problem and explain the answer step by step

can someone help me with this problem and show your work step by step

The switch makes contact with position b just before breaking contact with position a. As already mentioned, this is known as a make-before-break switch and is designed so that the switch does not interrupt the current in an inductive circuit. The interval of time between "making" and "breaking" is assumed to be negligible. The switch has been in the a position for a long time. At t = 0 the switch is thrown from position a to position b. What percentage of the initial energy stored in the inductor is dissipated in the 90 Ω resistor 1.2 ms after the switch is thrown from position a to position b?
