Basic DC Circuit Relationships

DC circuits can be completely analyzed with these four relationships.	Ohm's law	I = V/R
	Power relationship	P = VI
	Voltage Law	The net voltage change is equal to zero around any closed loop. (This is an application of the principle of conservation of energy.)
	Current Law	The electric current in = electric current out of any junction. (Conservation of charge)
