A 500W electric oven plugged into a 220 V source will consume an electric current of

Analyze the question: We are given the power of an oven (500 W) and the voltage of the source (220 V). We need to find the current it draws.

Concept: Electrical power is the product of voltage and current:

P = IV, so I = P / V

Solution:

• P = 500 W
• V = 220 V

I = P / V = 500 / 220

I = 2.27 A (to 2 decimal places)

Check against the options:

• A. 4.88 A: too large
• B. 2.27 A: matches our result
• C. 6.43 A: too large
• D. 3.23 A: does not match

Answer: B (2.27 A)

Tip: Whenever you see power and voltage together and are asked for current, use I = P/V. Quickly estimate to eliminate options: 500 ÷ 220 is a little over 2 (since 220 × 2 = 440), so the answer must be just above 2 A. That leaves only 2.27 A. Related forms to remember: P = I²R and P = V²/R.
