A bulb of resistance 280 Ω is supplied with a 200   V A C supply. What is the peak current?

A bulb of resistance 280Ω is supplied with a 200 V AC supply. What is the peak current?
  1. Nearly 1 A
  2. Nearly 2 A
  3. Nearly 1.4 A
  4. Nearly 2.8 A

Solution

Peak voltage, Vpeak=2V

Peak current, Ipeak=VpeakR=2VR

⇒Ipeak=2×200280≈1 A
