Question

An electric heater draws a current of 5 A when the supply voltage is 200 V. The power of 5 such heaters will be:

विकल्प

• 5000 W

• 4500 W

• 4000 W

• none of these

Answer 1

5000 W

Explanation:

Power of one heater (P) = V × I

= 200 × 5

= 1000 W

For five heaters, the total power is $$5 \times 1000 = 5000\ \mathrm{W}$$.
