Solution

The resistance of an element in an electric heater can be calculated using Ohm's Law, which states that the resistance (R) is equal to the voltage (V) divided by the current (I).

Given: Voltage (V) = 240 V Current (I) = 0.25 A

We can substitute these values into Ohm's Law:

R = V / I R = 240 V / 0.25 A R = 960 Ω

So, the resistance of the element in the electric heater is 960 Ω. Therefore, the correct answer is a.960 Ω.
