5:10 PM Sat Jul 9 < Lab 07 Parallel and Series Circuits.docx PART IV: INTRODUCING THE IDEA OF 'POWER' Resistors heat up when current passes through them. The more resistance there is, the more they heat up. When this happens, we can discuss "How much power do they dissipate?", which just means, "How many Joules of energy are they releasing every second?". Power can be thought of as how quickly 'Q' moves. 'Q' is just a variable for heat energy, measured in Joules (like any other type of energy). In electric circuits, there are several different ways you can calculate power. Here's the easiest: POWER EQUALS CURRENT MES VOLTAGE OR P = IV So if I know how much current is passing through a resistor, and I know the voltage drop across that resistor, this can be used to easily find how much power each resistor dissipates. Your job is now to find which resistor out of all three sections above dissipates the least amount of power, and which one dissipates the most power. Show your work and your reasoning below: A
