What will be the intensity if the lamp is short-circuited? Help me, it's for today and I don't understand anything. The teacher did not explain anything.

As well says Joaquin, the initial intensity will be of 5.24 but if you factor in the power of the bulb: By 5.24 x 220V =1152,8 W If you look at the bulb you'll see that it doesn't have that power, not by a long shot, it is because the resistance this cold and lets in more current when they warm up, increases its resistance and causes it to pass less current. In accordance with the consumption marked by the light bulb. It is important to understand that a light-bulb turning on can consume 10 times more of what it consumes once it has warmed up (few seconds after)
