An electric lamb of `100 Omega`, a toaster of resistance `50 Omega` and a water filter of resistance `500 Omega` are connected in parallel to a `220 V` source. What is the resistance of an electric iron connected to the same source that takes as much current as all three appliances ans what is the current through it ?

Explanation

To solve the problem step by step, we will first find the total current drawn by the three appliances connected in parallel, and then we will determine the resistance of the electric iron that draws the same current when connected to the same voltage source.

### Step 1: Calculate the current through each appliance

1. **Electric Lamp (R1 = 100 Ω)**:
- Voltage (V) = 220 V
- Current (I1) = V / R1 = 220 V / 100 Ω = 2.2 A
