Find currents using KVL


Find resistor currents using KVL.
Resistive Circuit

Solution:

R_1 and V_1 are parallel. So the voltage across R_1 is equal to V_1. This can be also calculated using KVL in the left hand side loop:

Problem 1-12: Using Voltage Sources to Determine Node Voltages


Determine the power of  R_1, R_2 and  Vs_1. (Hint: there is no need to use nodal analysis; voltages between nodes can be easily found by the voltage sources.)
Voltage sources can be used to fing node voltages

Solution
KVL around the loop
 V_{R_1}= Vs_1 = 10v \rightarrow P_{R_1}=\frac{V_{R_1}^2}{R_1}=50 W
