Two lamps one rated 100 w at 220 v ,the other 60w at 220 v are connected in parallel to electric main supply.(what current is drawn from the line if the supply voltage is 220v) ? What is the meaning of the line which is in bracket .which line is this question asking about?
Here the question asked is how much is the current flowing through the circuit.
Since bulbs are connected in parallel, the potential difference across each of them will be 220V.
We know that, Power = voltage x current
=> current drawn from the line = 100 / 220 + 60 / 220 = 0.727A.
