Question

An electric heater rated at 1500watt -250v calculate the resistance of wire of electric heater

Answer 1

Answer:

41.66 ohms

Explanation:

For a 1500 watt, 250 volts heater, considering the power factor at unity means 1, and as per the formula W =V ×V /R, or R =V ×V /W, so it will be, 250 ×250 /1500, 62500 /1500 =41.66 ohms is the resistance of the heater.
