Description : The transconductance of a JFET is computed at constant VDS by: (1) Ratio of change in Idto change of Vgs (2) Ratio of change inVgs to change ofId (3) Product of change in Vgs to change of Id (4) Ratio of change in Vds to change of Id

Answer : The transconductance of a JFET is computed at constant VDS by: Ratio of change in Id to change of Vgs
