(a) positive
(d) the separations of the grid from the cathode and the anode.
(d) the temperature of the cathode.
The correct answer is (b) (c) (d)
(a) Balmer Series (b) Lymen Series (c) Pfund Series
In SO2 molecule there are two bond pairs and one lone pair of electron .Due to repulsion by lone pair its bond angle decreases from 120° to 119.5° hence it...
rp = 2KΩ = 2 x 103Ω gm = 2millimho = 2 x 10–3mho μ = rp x gm = 2 x 103 x 2 x 10–3 = 4Amplification factor is 4.
Dynamic Plate Resistance rp = 10KΩ = 104Ω δIp = ? δVp = 220 – 220 = 20V δIp = (δVp/rp)/ Vg = constant. = 20/104 = 0.002A = 2mA
(ii)Visible Region
(d) Tropical region
