Q. 2 bulbs of rating 230V, 60W are connected in series and parallel across a 230V supply. The power delivered by one bulb in both cases are
Solution:
In series connection, voltage across the bulb is halved so power becomes one-forth of 60W = 15W.
In parallel connection, the power remains 60W itself.
