Question

QUE RE 150 050 45V Which equation best describes the voltage loop equation for the LOWER loop going counterclockwise starting at node 'a: 45 -0.513 +1.513 = 0 O-2.512-18V +0.51, +611 = 0 45 -0.513 +1.513 - 611 = 0 45 -0.51,-1.513 – 671 = 0 Type here to search o E D.

Answer 1

Here when we apply the kVL loop equation in the lower loop going counterclockwise we will get,

Here the main concept we should take in mind that while writing these type of voltage loop equation then current exiting from positive terminals of element will be positive and current entering into the positive terminal of the elements like resistor will shows negative voltage while writing the equation so that, based on these idea we will have the equation as

45 - 0.5 I3 - 1.5 I3 = 0

Hence option A is correct here.
