Measurement of the social construction of knowledge: validation

41 Previous validation and reliability studies of instruments One example serving as background for the KSocialC questionnaire design is a study conducted by Hernández et al that contemplated three research questions related to innovation, laboratories' trends, and their importance for the academic communityData were TddƟ = i1i2dM ⇒Td = i1i2dM/dƟ The above equation gives the deflecting torque in electrodynamics or electrodynamometer instruments It can be seen that deflecting torque depends upon the multiplication of instantaneous value of current and rate of change of mutual inductance between the fixed and moving coilTorque Equation in Electrodynamometer Instruments
