Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.this becomes the circuit
now 2 ohm = other resistances
so Rx = 3/2
@hardcoreisdead i think you can figure this out once you write the exp for current through the 2 ohm resistor.. it's 5/ (3R/3+R + 3).. so obv setting R=0 will give the maximum value. we dont use max power theorem when we can change any of the other resistors ig
on the other hand if you look at R (variable wala), you can say that power would be maximum in R if R = other resistors
but over here that'd be also not right to say ig, since it's in parallel with the 3 ohm one, and we cant prolly independently find out the remaining resistance
but yeah in gen with such qs, variable resistor me if you wanna maximise the power then u can say that it should be equal to the other resistors
but if we have a fixed value and we have to change the others to maximise power through the fixed value one then obv minimising the resistance would be the best choice
hmmm makes sense
