About This Product
Turning the crank lets students see their own energy converted into d.c. electricity. Turned slowly, the generator lights a bulb only dimly; turned faster, the bulb becomes brighter. Reversing the direction of turning reverses the output polarity, and the supplied 1 m twin lead ends in a pair of crocodile clips.
Frequently Asked Questions
Q1. What happens when the handle is turned faster? A connected bulb glows dimly when the handle is turned slowly and becomes brighter as the handle is turned faster.
Q2. How is the output polarity changed? The polarity of the d.c. output depends on the direction in which the handle is turned, so turning it the other way reverses it.
