Answer:
The resistance of the heater is 44 ohms.
Step-by-step explanation:
Given that,
Voltage of electric heater, V = 440 volts
Current drawn by the heater, I = 10 A
We need to find the resistance of the heater. It is a case of Ohm's law. Its mathematical form is given by :

R is resistance of the heater

So, the resistance of the heater is 44 ohms. Hence, this is the required solution.
