Which touchscreen technology changes the flow of electricity across the screen when the screen is touched?
A
Capacitive
B
Infra-red
C
Resistive
D
None of the above
Explanation: 

Detailed explanation-1: -A touch screen technology known as “surface capacitive” employs an electric field and a conductive-coated layer to detect touch instructions. Touch screens with a surface capacitive feature have a top layer. A conductive substance is placed over this top layer.

Detailed explanation-2: -The touch sensor can be one of three types: resistive, surface acoustic wave, or capacitive. Resistive and capacitive are the most common and are quite ingenious.

Detailed explanation-3: -Applications with capacitive touchscreens allow only finger or conductive stylus. Resistive touchscreen applications work fine with direct finger touch, gloved finger, and a stylus.
