Match the following. a. Apollo aircraft (i) Anode Zn Cathode Carbon rod

Question

Match the following:

a.	Apollo aircraft	(i)	\(\underset{\underset{Zn}{}}{\text{Anode}}\)  \(\underset{\underset{\text{Carbon rod}}{}}{\text{Cathode}}\)
b.	Invertor cell	(ii)	\(\underset{\underset{Pb}{}}{\text{Anode}}\)   \(\underset{\underset{PbO_2}{}}{\text{Cathode}}\)
c.	Transistor	(iii)	\(\underset{\underset{\text{Zn / Hg}}{}}{\text{Anode}}\)   \(\underset{\underset{\text{HgO}}{}}{\text{Cathode}}\)
d.	Hearing aid	(iv)	Hydrogen   Fuel cell

 

	a	b	c	d
(1)	(iv)	(ii)	(i)	(iii)
(2)	(i)	(ii)	(iii)	(iv)
(3)	(ii)	(iii)	(iv)	(i)
(4)	(i)	(ii)	(iv)	(iii)

Answer 1

Correct option is: (1) (iv) (ii) (i) (iii) 

(a) Apollo aircraft → Hydrogen Fuel cell 

(b) Invertor cell → Anode (Pb), Cathode (PbO₂) 

(c) Transistor → Anode (Zn), Cathode (Carbon rod) 

(d) Hearing aid → Anode (Zn/Hg), Cathode (HgO)
