Question

A 100w, 220volt lamp takes a current of _.

Answer 1

P = VI

100 w= 220v . I

I = 100/220

I = 10 /22 Ampere or 5/11 Ampere

Answer 2

Answer : The Current (I) passing through lamp 0.455 Ampere Step-by-step Explanation: Given : Power of the lamp (P) = 100W Operating voltage (V) = 220 V To find : Current = ? We know that , Power(P) = Current(I) × Voltage (V) Substituting the given value in above formula we get, 100 = Current (I) × 220 Current (I) = 100/220 Current (I) = 10/22 = 5/11 Current (I) = 0.455 Ampere Hence the Current (I) passing through lamp 0.455 Ampere
