Question

Two lamps one rated 100 W 220 V, and the other 60 W 220 V, are connected in parallel to electric mains supply. Find the currents drawn by two bulbs from the line, if the supply voltage is 220 V.
Medium

Solution

Current in 1st bulb, I₁ = P₁/ V₁ = 100/220 = 5/11 A or 0.45 A Current in 2nd bulb, I₂= P₂ / V₂ = 60/ 220 = 3/ 11 A or 0.27 A
