In the given material, which device is described as amplifying or switching on an electrical signal?

• A. Translator— amplifies or switches on electrical signal
• B. Diode— limits current
• C. Inductor— stores energy
• D. Capacitor— stores energy

Answer: (A)

Amplification and switching are functions handled by a transistor in most electronics. A transistor lets a small input signal control a larger current, enabling you to boost signal strength (amplification) or turn current on and off (switching). In the material, this device is described as a translator that amplifies or switches an electrical signal, matching the described role. The other devices don’t perform amplification or switching: a diode controls current direction but doesn’t amplify; an inductor stores energy in a magnetic field; a capacitor stores energy in an electric field. So the translator, as described, is the best fit for amplifying or switching.
