Power Questions

An electric bulb is rated $220\text{V}-100\text{W}$. The power consumed by it when operated on $110\text{V}$ will be:

In an a.c. circuit the voltage applied is $E=E_0\sin \omega t$. The resulting current in the circuit is $I=I_0\sin \left(\omega t-\frac{\pi }{2}\right)$. The power consumption in the circuit is given by:

A body of mass $m$ is accelerated uniformly from rest to a speed $v$ in a time $T$. The instantaneous power delivered to the body as a function time is given by:

A $220\text{volt}$, $1000\text{watt}$ bulb is connected across a $110\text{volt}$ mains supply. The power consumed will be:

A body is moved along a straight line by a machine delivering a constant power. The distance moved by the body in time $t$ is proportional to:

Two electric bulbs marked $25\text{W}-220\text{V}$ and $100\text{W}-220\text{V}$ are connected in series to a $440\text{V}$ supply. Which of the bulbs will fuse?
