(ii) If potential difference of 50 V is applied to its terminal, calculate the current
flowing through it.
(iii) What would happen if one of the bulbs got fused or turned dead? Also state
what needs to be done in such situation.

Answer 1

Answer:I) Total Resistance= R1+R2+R3...Rn

So, Total Resistance=20+20+20+20+20

=100ohm
