Hello Savannah, A circuit overload is defined as the flow of electricity into conductors or devices at a level that exceeds their capacity. What does that mean?!? First, where do overloads occur? They can occur in any electronic device. Inside every electronic device (like your microwave, remote control, Nintendo64, etc.) are small components that make use of electricity, performing a function for you (cooking your food, changing the channel, playing a video-game, etc.). The electronic components inside the device are rated to handle a certain amount of electrical current (the movement of electrons through the component). When this capacity is exceeded (when too many electrons are pushed through the device), damage can occur. This is typically because electrical current generates heat, and the components in your device are designed to dissipate a certain amount of expected heat. If the current exceeds the current-rating, the heat produced typically exceeds the heat-rating, usually burning up the component, rendering it non-functional. I hope this helps! Learning about basic electrical properties (such as current and voltage) and circuitry components (such as resistors, inductors and capacitors) will certainly augment your understanding! Yahoo! searches for "Electricity, Magnetism and Physics" may prove useful! Take Care and Regards, Justin
