Solution Summary

In a given electric circuit, by using Kirchhoff current and voltage law, currents are estimated in associated resistances. Also, power dissipation in the resistances are estimated.

Solution Preview

Let us assume current through R be I3 and comping out of battery of 12 V, i.e., all 3 currents are incident towards a junction.


E1 = 13 V
E2 = 14 V
E3 = 12 V

R1 = 1 ohm
R2 = 2 ohm
R = 3 ohm

At one of the two junctions, by Kirchhoff's current law (KCL),

I1 + I2 + I3 = 0 ...(1)

  • " In question 2, you incorrectly add in the $3.00 dividend that was just paid to determine the value of the stock price using the dividend discount model. In question 4 response, it should have also been recognized that dividend discount models are not useful if any of the parameters used in the model are inaccurate. "
