An electric bulb, when connected to a 200 V source, draws a current of 0.40 A. Calculate the power and resistance of the bulb. CBSE Class X Science SA 2 (3 Marks)

Answer»

resistance of the bulb = 500 Ωpower of the bulb. = 80WExplanation: ELECTRIC bulb,  connected to a 200 V sourceCurrent Drawn = 0.4 ACurrent = VOLTAGE / Resistance=> Resistance = Voltage / Current=> Resistance = 200/(0.4)=> Resistance = 500 Ωresistance of the bulb = 500 ΩPower =,Voltage * Current=> POWER = 200 * 0.4=> Power = 80 Wpower of the bulb. = 80W
