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?

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