Resultant Vector Formula Derivation. From triangle OBC tanphi fracBCOCfracBCOAAC tanphi fracQsinTheta PQcosTheta therefore phi tan-1fracQsinTheta PQcosTheta. Vector Diagram of Resultant Voltage Here line OB is the horizontal current reference OA is the voltage across the resistive component and it is in phase with current OC represents inductive voltage that is 90 degrees in front of current OD will give resulting supply voltage.
The weight of the unknown body If W is the actual weight of the body then the percentage error in the experiment can be calculated using the equation. Above equation is the magnitude of the resultant vector. From triangle OCB In triangle ABC Also Magnitude of resultant.
Let th be the angle between P and Q.
The weight of the unknown body If W is the actual weight of the body then the percentage error in the experiment can be calculated using the equation. Vector Diagram of Resultant Voltage Here line OB is the horizontal current reference OA is the voltage across the resistive component and it is in phase with current OC represents inductive voltage that is 90 degrees in front of current OD will give resulting supply voltage. The direction of the resultant is the same as the original vector. The resultant vector formula is large overrightarrowRsqrtoverrightarrowx2overrightarrowy2 Solved Example.
