An electric bulb is labeled 240v, 60w. How much current is taken by the bulb?

Current = 0.25 A

Electric power i: electrical energy per unit time  

P = watt  

W = electrical energy, J  

t = time, s  

or

P = V.I  

V=voltages, volt

I=current,A

An electric bulb is labeled 240v, 60w,

So,

P = 60 watt

V=240 volt

true. earthquakes are felt whenever there is a slip around a fault in the rocks below the earth. this reorientation of faults create sesmic waves and is known as earthquake, the severity of which is measured in richter scale. these are more prominent in hilly regions as the rocks usually form faults to balance the pressures on it.
