Question

If a 60 W bulb and a 100 W bulb are connected in series in a circuit, across which bulb will there be the greater voltage drop? The greater voltage drop Is across the 100 watt bulb in series. The voltage drop is the same across each bulb. The greater voltage drop Is across the 60 watt bulb in series. How about if they are connected in parallel? The voltage drop is the same across each bulb. The greater voltage drop is across the 60 watt bulb In series. The greater voltage drop Is across the 100 watt bulb in series.

Explanation / Answer

1) As we know that P = V^2 /R So larger the power, larger is the voltage drop. Similarly P = VI Current is same in series and P is directly proportional to V, so larger P, larger voltage drop

So 100 W bulb having greater voltage drop. Option 1 is correct

2) If they are connected in parallel, there will be no difference in voltage drop.

In parallel combination, they carry same voltage.

so hrer option 1 is correct
