The current in a 60 watt, 120 volt lamp is ___.
lamp 120 12° 0.7 m 5.0 m ground 1.A bicycle light bulb runs off a 6.0 volt battery, and draws a current of 0.50 ampere. 80% of the electrical power input is converted into radiant output, with a luminous efficacy of 16 lumen/watt. A reflector directs all the light from the bulb into a uniform cone of light, of half-angle 12°. The lamp is mounted on a bicycle at a height of 0.70 m above the ground, and the centre...
