(a) A – cathode B – Anode C – Cooling fins
(b) (i) increase the p.d at the anode (B)
(ii) : increase the cathode heater current
(c) Tungsten:- It has a high melting point so the heat produced will not melt it easily
(d) Copper – it is used to cool/conduct heat away from the anode
(e) So that the electrons do not collide with gas molecules which could result in loss of energy.
