Kirchoff’s Rules and Complex DC Circuits

KIRCHOFF’S RULES
Junction Rule The current entering a junction equals the current leaving a junction.
Loop Rule The potential differences around any closed loop sum to zero.
+ vs - Moving across a battery from negative to positive terminal is +ΔV.
Moving across a battery from positive to negative terminal is -ΔV.
Moving across a resistor in the direction current is defined is +ΔV.
Moving across a resistor opposite the direction current is defined is -ΔV.
