An electric iron is rated as 220 V-850W. What is the resistance of its heating element ? How much current will it draw when the rated voltage is applied on it ?

Explanation

To solve the problem, we need to find the resistance of the heating element of the electric iron and the current it draws when the rated voltage is applied. Here’s how to do it step by step:

### Step 1: Identify the given values
- Voltage (V) = 220 V
- Power (P) = 850 W

### Step 2: Use the power formula to find the current
The power (P) of an electrical device can be expressed in terms of voltage (V) and current (I) using the formula:
