Question

A torque is applied to a generator connected a to a lightbulb which causes the generator to spin and the bulb to brighten. If the bulb burns out,creating an open circuit, the torque required to spin the generator will be _____Smaller?Greater?The same?

Answer 1

Step-by-step explanation:

When the bulb burns out, there is a reduction in load. The power produced by the generator is proportional to the rotational speed and torque. Since there is a reduction in load, A decreased load implies lesser current and lesser torque. Thus, the answer is

Smaller
