SINGLE LOOP CIRCUITS
BACKGROUND: USING KVL AND KCL WE CAN
WRITE ENOUGH EQUATIONS TO ANALYZE ANY
LINEAR CIRCUIT. WE NOW START THE STUDY
OF SYSTEMATIC, AND EFFICIENT, WAYS OF
USING THE FUNDAMENTAL CIRCUIT LAWS
WRITE 5 KCL EQS
OR DETERMINE THE
ONLY CURRENT
FLOWING
VOLTAGE DIVISION: THE SIMPLEST CASE
THE PLAN
• BEGIN WITH THE SIMPLEST ONE LOOP CIRCUIT
• EXTEND RESULTS TO MULTIPLE SOURCE
• AND MULTIPLE RESISTORS CIRCUITS
KVL ON
