A circuit has three parts. They are a power source, a load, and connecting wire . If any part of a series circuit breaks, the circuit is open. As a result, none of the parts will work because current cannot flow . In a parallel circuit, each branch has its own path for electric current . Therefore, if any branch of a parallel circuit breaks, currents will still flow through the other branches . Use the Writing Frame to write the summary on another sheet of paper. Be sure to include the bold signal words. Keep this as a model of this Text Structure. 10 ... - tailieumienphi.vn
