Question

The power source of a camera flash is a 1.5 V d.c. battery. The flash circuit converts this to 1.5V a.c. which is then increased to 300V a.c.

Assuming there are no energy losses, describe how the potential difference can be increased from 1.5V a.c. to 300V a.c.

  

Answer 1

Solution;

The voltage can be increased by the use of a step up transformers.
