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)
For closed ...
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.
Simple Resistive Circuits: Voltage drop, Power rating
Consider the circuit in the attachment when answering the questions posed below.
a) What value of Ix will result in a voltage drop of 16 V across the 10 k Ohm resistor?
b) To reduce cost, it is desired that each resistor in the circuit have the same power rating. Using the results of (a) what power rating - to the nearest 0.1 W - is needed?View Full Posting Details
