Question
Consider a part of an electrical network as shown below. Some node voltages, and the current flowing through the resistor are as indicated.The voltage (in Volts) at node is ______.
Correct answer
(A) 20/3
Solution
Let the node where the , , and resistors meet be node .
Thus, the correct option is (A).
1.Calculate the voltage at node (): The current through the resistor is flowing from the source to node .
.2.Calculate the current () flowing from the node to node : This current passes through the and resistors in series.
.3.Calculate the voltage at node (): Node is between the node and the resistor.
.Thus, the correct option is (A).
