Question
Task: Power Calculations Calculate the power from a 120V can open draws 2.2A of current Calculate the power a TV connected to a 120V line that draws 1.1A of current. Find the voltage across a 1200W toaster which draws 10A of current. What is the potential difference in a circuit that has 24 A of current and 6W c power in it?

Answer
* **Calculation 1: Power of a can opener**Power (P) is calculated using the formula: P = V * I, where V is voltage and I is current.Given: V = 120V, I = 2.2AP = 120V * 2.2A = 264 Watts* **Calculation 2: Power of a TV**Given: V = 120V, I = 1.1AP = 120V * 1.1A = 132 Watts* **Calculation 3: Voltage across a toaster**Given: P = 1200W, I = 10AWe can rearrange the power formula to solve for voltage: V = P / IV = 1200W / 10A = 120V* **Calculation 4: Potential difference in a circuit**Given: I = 24A, P = 6WAgain, using the rearranged power formula: V = P / IV = 6W / 24A = 0.25V
