Electronic circuits and electric circuits are used together in many everyday systems, especially where power delivery and intelligent control have to work hand in hand. Here are two clear, exam‑style examples.

1. Home Automation / Smart Home System

In a modern smart home, you have both power wiring and smart control electronics working together in the same devices.

  • The electric circuits carry mains electricity from the distribution board to lights, wall sockets, fans, and appliances. They provide the actual power that makes bulbs glow and motors turn.
  • The electronic circuits are inside smart switches, motion sensors, Wi‑Fi modules, and microcontrollers. They sense movement, receive app or voice commands, and decide when to switch the power on or off.
  • When you tap a button in a phone app to turn on a smart light, an electronic circuit processes the wireless signal, then activates a relay or triac in the electric circuit, which finally supplies power to the lamp.

So in one system, the electric circuit handles high‑power delivery, and the electronic circuit handles sensing, timing, and communication.

2. Television or Computer System

A TV or desktop computer is another classic place where both types of circuits operate together in one device.

  • The electric circuits in the power supply take AC from the wall and convert it to the required DC voltages, distributing power to different boards and sometimes driving high‑power parts like backlight LEDs or cooling fans.
  • The electronic circuits (microprocessors, signal processors, memory, graphics chips) handle all data processing: receiving the signal, decoding video and audio, generating images, and controlling the screen.
  • When you press the power button, an electronic control circuit detects the input and then instructs the power circuitry to connect or disconnect the main electric supply inside the TV or computer.

Again, the electric circuit is responsible for safely providing energy, while the electronic circuit is responsible for “thinking” and control logic in the device.

TL;DR:
Two examples of situations where electronic circuits and electric circuits are used together are:

  1. Smart home / home automation systems (power wiring + smart control electronics).
  2. Televisions or computers (power supply circuits + signal‑processing electronics).
