KIRCHHOFF VOLTAGE LAW (KVL)
KVL IS A CONSERVATION OF ENERGY PRINCIPLE
A POSITIVE CHARGE GAINS ENERGY AS IT MOVES
TO A POINT WITH HIGHER VOLTAGE AND RELEASES
ENERGY IF IT MOVES TO A POINT WITH LOWER
VOLTAGE
A “THOUGHT EXPERIMENT”
IF THE CHARGE COMES BACK TO THE SAME
INITIAL POINT THE NET ENERGY GAIN
MUST BE ZERO (Conservative network)
OTHERWISE THE CHARGE COULD END UP WITH
INFINITE ENERGY, OR SUPPLY AN INFINITE
AMOUNT OF ENERGY
KVL: THE ALGEBRAIC SUM OF VOLTAGE
DROPS AROUND ANY LOOP MUST BE ZERO
