    Actually, there is a difference between the deflection tube and CRO. The deflection tube consists of the gun but has only the Y plates which cause vertical movement of the beam. Its used to study properties of a beam of electrons. But, the CRO is more complex. Google both the deflection tube and...

    It is there in the syllabus. This is from the 2014 5054 physics syllabus Its not like thermonuclear astrophysics, its a simple concept. You just have to know what a diode is, what it does, how to include it in a circuit diagram and about rectifying AC currents

    Yes,diode is part of the syllabus. Ans is D since it clearly states RECTIFYING diode so only AC can be used in the rectification process so that's why A is wrong. The purpose of a diode is to allow current to pass only when its forward biased so even DC can pass. When AC passes, a forward biased...
