Question

What is the difference between a check box, radio button and a drop-down list?​

Answer 1

A transformer changes the magnitude of the input voltage. There are two types of transformer - Step-up and step-down transformer.

Step-up transformer increases the magnitude of voltage of primary coil whereas step-down transformer decreases the magnitude of voltage of primary coil.

Answer 2

There is a fundamental difference between them. In a checkbox group, a user can select more than one option. Each checkbox operates individually, so a user can toggle each response "on" and "off." Radio buttons, however, operate as a group and provide mutually exclusive selection values.
