In a balanced wheatstone bridge, instead of the arm having the galvanometer through which no current passes, we place a resistor of resistance X.
To find the equivalent resistance of the wheatstone bridge, do we need to add the resistance X

Why is it that when 3 bulbs of powers P1,P2 and P3 which have been manufactured to work on the same voltage V when connected in series, the bulb with the lowest wattage(power) will glow the brightest and will have the maximum resistance? Isn't the resistance supposed to reduce the current and hence the brightness of the bulbs? Also why is it the exact opposite when the bulbs are connected in parallel?
