NEET2022PhysicsAlternating CurrentActual
A standard filament lamp consumes 100 ~W when connected to 200 ~V a.c. mains supply. The peak current through the bulb will be :
Options
- A0.707 ~A
- B1 ~A
- C1.414 ~A
- D2 ~A
Correct answer
A. 0.707 ~A
Step-by-step solution
Power, aligned P & = I _ rms V _ rms I _ rms & = P V _ rms = 100 200 = 1 2 I ₀ & = 2 I _ rms I ₀ & = 2 1 2 I ₀ & = 1 2 =0.707 ~A aligned
