8) in photoelectric cell the current stops when the collecting plate is 1volt negative with respect to emitting plate. the what is maximum kinetic energy of electrons Share with your friends Share 0 Sanjay Singh answered this Dear student Maximum kinetic energy is Kmax=e×(stopping potential )Kmax=e×Vs=(1.6×10-19×1)J=1.6×10-19JRegards 2 View Full Answer
