Bulbs in $A$ glow brighter since the current flowing in is higher in $A$.

Vedclass · Answer

(B) In a series circuit $(A)$,the total resistance is $R_{eq} = 20R$,which leads to a lower current $I = V / (20R)$. Thus,the power dissipated in each bulb is $P = I^2R = V^2 / (400R)$,resulting in dim light.In a parallel circuit $(B)$,each bulb is connected directly to the supply voltage $V$. Thus,the power dissipated in each bulb is $P = V^2 / R$,which is significantly higher than in the series case.If one bulb blows in series $(A)$,the circuit is broken,and all bulbs stop glowing.If one bulb blows in parallel $(B)$,the other bulbs remain connected to the supply and continue to glow.Therefore,the statement that 'Bulbs in $A$ glow brighter' is false,as they glow dimmer than those in $B$.

Consider the following two circuits:
$A$: $20$ bulbs are connected in series to a power supply line.
$B$: $20$ bulbs identical to $A$ are connected in a parallel circuit to an identical power supply line.
