Resistor and RC Circuits  Problem 12:   Consider the circuit in the figure, with the current directions defined as shown. There are four resistors in this circuit (R1, R2, R3, and R4) and four batteries with emfs ℰ1 = 15.5 V, ℰ2 = 3.5 V, ℰ3 = 14 V, and ℰ4 = 27.3 V, each with internal resistance given by ri as marked in the figure. Part (a)  Calculate the current I1 in amps.  Part (b)  Calculate the current I2 in amps. Part (c)  Calculate the current I3 in amps.

Using mesh current analysis, find the currents i1 and i2 for the circuit of Figure P3.14.

Mesh current methods can greatly reduce the calculations as compared to Kirchhoff’s voltage and current laws in circuits with multiple branches. Refer to the textbook reading and the lecture for this week to answer the following post. Describe, step-by-step, the steps required to calculate all currents and voltage drops in a DC network using the Mesh Current Method.

To extend the useful range of a voltmeter, an additional resistor, Rseries, is placed in series with the voltmeter as shown in the figure. If the internal resistance of the voltmeter is Ri,V, determine the resistance that the added series resistor has to have to extend the useful range of the voltmeter by a factor N. Then, calculate the resistance the series resistor must have to allow a voltmeter with an internal resistance of 1.00 MΩ and a maximum range of 1.00 V to measure potential differences up to 100. V. What fraction of the total 100.-V potential drop occurs across the voltmeter, and what fraction of that drop occurs across the added series resistor?

can someone show me step by step how to do this problem and explain the concepts A device, shown in Figure P3.5a, can be modeled by a current source in parallel with a resistance. The relationship between the current through the device, iX, and the voltage across the device, vX, is given in the plot in Figure P3.5b. a) Find a model for the device that would be valid when current is in the range 1[mA] < iX < 5[mA]. This model must have numerical values for the current and resistance, and the polarities with respect to vX and iX should be shown in a diagram. b) A voltage source is applied across the device so that vX = 10[V]. Find the power delivered by the device in this situation.

An electric toothbrush has a base designed to hold the toothbrush handle when not in use. As shown, the handle has a cylindrical hole that fits loosely over a matching cylinder on the base. When the handle is placed on the base, a changing current in a solenoid inside the base cylinder induces a current in a coil inside the handle. This induced current charges the battery in the handle. We can model the base as a solenoid of length ℓ with NB turns (as shown), carrying a current i, and having a cross-sectional area A. The handle coil contains NH turns and completely surrounds the base coil. Find the mutual inductance of the system.
