LEDs are used in _ calculators.
Correct answer: A. Electronic
- A. Electronic
- B. Digital
- C. Lamp
- D. Panel
Explanation
Electronic calculators typically use various electronic components, including integrated circuits (ICs), transistors, resistors, capacitors, and sometimes LEDs or LCDs for the display. These calculators perform mathematical operations electronically, utilizing the components to process and display numerical information accurately and quickly. The electronic components work together to perform calculations, store data temporarily, and display the results on the screen.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
