[@nimuvala5361]

The short method of finding power of second bulb if power and voltage of first bulb is given: You can use unitary method, if you use unitary method, multiply your answer by multiple of the potential of first bulb { V1 } given in question. For example, a bulb is given of 220 V and 100 W and second bulb is given of 110 V, then find power in second bulb.... Answer: 220V -> 100W 110V -> x x = 110V * 100W / 220V x = 50 110 is 1/2 multiple of 220 i.e, V2 = 1/2 V1 therefore, now multiply the multiple of V1 with x P = x * 1/2 P = 50 * 1/2 P = 25W keep units in SI units only

Sir u have done a mistake . At 40:46 ,for calculating resistance of each bulb u have taken p.d. of each bulb as 220 which is wrong because pd of whole combination is 220 and not across each bulb

[@vestoic_o77]

yep,but how it is done in correct manner now?

[@arsalanahmad907]

yeah! this is the same doubt i have..

[@sushilabeniwal4706]

No this is correct. Because the power rating is done on the basis of the Indian system that is 220V and the resistance is decided on the basis of that only.

No bro, you need to use current in the upper circuit cause they are in series. So W1=i^2 R1 and W2=i^2R2 and replace .i with V/(R1+R2) AND FOR W3= V^2/R3. HOPE IT HELPS 😃

Great sympathy for resistance by sir 😂

[@BHASKAR-_-]

My method for last problem- Branch of Bulb 3 and (2and1) have same potential difference (parallel), and also bulb 2 potential will decrease due to series with 1. Then On comparing 3 and 2 where v differs i.e for 2 it is lesser compared to 3, taking p=vsquare/r we can get that 3>2 since r is constant and also the eqn for p used is appropriate. From checking options we can get the problem sol. here... And also if we compare 1 and 2 they have same i(series) so we can happily use p=isquare r Here r1 is less than r2 hence 2>1 so 3>2>1 Hope you got my point Let me know if there is any mistake in my sol. Jai PW P.S-r is same for both 3 and 2 not constant ;)
