Question

A 220 volt and 800 watt electric kettle and three 220 volt and 100 watt bulbs are connected in parallel. On connecting this combination with 220 volt electric supply, the total current will be

• A. 0.15 ampere
• B. 5.0 ampere
• C. 5.5 ampere
• D. 6.9 ampere

Answer 1

Answer: (B)

5.0 ampere

Answer 2

Total power$P = (800 + 3 \times 100)$

Also $P = Vi$ ⇒ $1100 = 220 \times i$ ⇒ $i = 5A$
