Question 1 Report
An electric iron is rated 1000W, 230V. What is the resistance of its elements?
Answer Details
The formula for calculating resistance is R = V/I, where R is the resistance in ohms, V is the voltage in volts, and I is the current in amperes.
First, we need to find the current flowing through the iron. We can use the formula P = VI, where P is the power in watts. We know that the power of the iron is 1000W and the voltage is 230V, so we can rearrange the formula to find the current:
I = P/V = 1000/230 = 4.35A
Now that we have the current, we can use the formula R = V/I to find the resistance. We know the voltage is 230V, so:
R = V/I = 230/4.35 = 52.9Ω
Therefore, the resistance of the iron's heating element is 52.9Ω. Answer is correct.
