Question

Equipment such as geysers and air conditioners, compared to light bulbs and fans, require:

A.

less power

B.

less voltage

C.

higher voltage

D.

higher power

Correct option is D

Correct Answer: D Higher power

Explanation:

Electrical equipment such as geysers and air conditioners require significantly higher power compared to devices like light bulbs and fans. The power consumption of an electrical device is given by:

P=VI

where:

  • P= Power (in watts)
  • V = Voltage (in volts)
  • I = Current (in amperes)

Why do geysers and air conditioners need higher power?

  • Geysers require power for heating water, which demands a high energy input, typically ranging from 1500W to 3000W.
  • Air conditioners operate compressors and cooling systems, consuming around 1500W to 5000W depending on capacity.
  • In contrast, light bulbs (LEDs and CFLs) consume only 5W to 100W, and fans usually operate at 50W to 100W.
  • These high-power appliances draw more current, leading to higher electricity usage.

Thus, geysers and air conditioners require higher power to function efficiently.

Information Booster:

  • Power-hungry appliances such as geysers, ACs, and ovens require dedicated wiring and high current capacity.
  • Air conditioners use compressors that consume more energy than regular electric motors.
  • Water heaters use resistive heating elements, which convert electrical energy into heat with high efficiency.
  • LED bulbs consume significantly less power than traditional incandescent bulbs.
  • Overloading circuits with high-power devices can lead to tripping or even electrical fires if proper wiring isn't used.
