IF THE CIRCUIT CONTAINS ONLY INDEPENDENT
SOURCE THE MESH EQUATIONS CAN BE WRITTEN
“BY INSPECTION”
THE RIGHT HAND SIDE IS THE ALGEBRAIC SUM
OF
VOLTAGE SOURCES AROUND THE LOOP
(VOLTAGE RISES - VOLTAGE DROPS)
MUST HAVE
ALL MESH CURRENTS WITH THE
SAME ORIENTATION
IN LOOP K
THE COEFFICENT OF Ik IS THE SUM OF
RESISTANCES AROUND THE LOOP.
THE COEFFICIENT OF Ij IS THE SUM OF
RESISTANCES COMMON TO BOTH k AND j AND
WITH A NEGATIVE SIGN.
