PARALLEL RCL CIRCUITS

Department of Defense - Description: BEGINS BY CONSTRUCTING A PARALLEL RCL CIRCUIT AND POINTING OUT THAT EACH INDIVIDUAL BRANCH CURRENT IS INDEPENDENT OF OTHER BRANCH CURRENTS. COMPARES THE TIME-PHASE RELATIONSHIP OF BRANCH CURRENTS THROUGH REACTIVE COMPONENTS. A PROBLEM IS GRAPHICALLY SOLVED FOR TOTAL CURRENT USING VECTOR ANALYSIS AND THEN IS SOLVED BY THE SAME CURRENT USING PYTHAGOREAN THEOREM. DETERMINES PHASE ANGLE BY A PROTRACTOR AND BY A TRIGONOMETRIC FUNCTION. REVIEWS REACTIVE, TRUE, AND POWER FACTOR FORMULAS. CONCLUDES BY SHOWING A CURRENT VECTOR FIRST WITH A LEADING PHASE ANGLE AND THEN WITH A LAGGING PHASE ANGLE. - PIN 11352
