a)Explain all possible basic strategies needed to work Kirchhoff's voltage and current law questions of circuits.Not necessarily just defining the concepts but throwing more light on how the loop and current directions affect the values(either positive or negative). Also give basic strategies to solve parallel and series connection or both.Also talk about tricks to find voltage drop across resistors.Kindly explain it to the basic level.Basically how to determine a Kichhoff's Voltage and current equation using direction of current and loop.Thank...
