Question
**Problem Statement:**

A coffee-maker (18 Ω) and a toaster (16 Ω) are connected in parallel to the same 120-V outlet in a kitchen. How much total power is supplied to the two appliances when both are turned on?

**Input Fields:**

- **Number:** [Input box]
- **Units:** [Dropdown menu]

**Instructions:**

To solve this problem, use the formula for power in parallel circuits. Apply Ohm's Law and the power formula:

1. **Find the power consumed by each appliance individually:**
   - Power (P) = Voltage (V)² / Resistance (R)

2. **Calculate the power for the coffee-maker:**
   - P_coffee-maker = 120² / 18

3. **Calculate the power for the toaster:**
   - P_toaster = 120² / 16

4. **Add the power of both appliances to find the total power.**

Be sure to enter your answer in the input box and select the correct units from the dropdown menu.
