Question

A coil in a simple generator has 200 turns.Now the number of turns in the coil increases to 500. What will be its effect:

• A. current produced will increase
• B. voltage produced will increase
• C. both
• D. none

Answer 1

The correct option is B voltage produced will increase

By law of conservation of energy, mechanical power converted =electrical power produced assuming no losses

i.e. $VI=$ constant.

When turns are increased, voltage induced increases, since voltage is proportional to to number of turns.

Hence, current reduces.
