Q.1 In series connection, why does current remain same across the resistors but potential difference different? In parallel connection, why does potential difference remain same across the resistors but current different?
Q.2 In series combination of resistors, why does resistance increase and current flowing through the circuit decrease? In parallel combination, why does resistance decrease and current flowing the circuit increase?

Two lamps, one rated 100 W at 220 V and the other 200W at 220 V are connected (i) in series and (ii) in parallel ot electric main supply of 220V. Find the current drawn in each case. In this question I'm able to find the answer for parallel connection in another way but able to do so for series if I follow the same methodology We know, the potential difference across each of the lamps is same so, 1/R1 + 1/R2 = 1/Rp Multiplying V^2 on both sides of the equation, I get V^2/R1 + V^2/R2 = V^2/Rp Which is technically saying, P1 + P2 = Pp Doing so, I get Pp = 300W and current drawn by the lamps is Pp = VI 300 = 220*I I = 15/11 = 1.36 A im not able to find an analogy like this for series pls help
