Electrical Engineering A circular cathode and a circular anode each of radius a = 20 mm are separated d = 40 mm apart and connected to a potential difference V = 100 V. The cathode is made of a potassium-based compound with a work function e0 = 1.6 eV and a quantum efficiency h = 18%. The answer in the back of the book is 0.142 A which idk how they got it Anode a Radiation V Cathode
