| Question | Answer |
|---|---|
| A ciricut may contain more than one___ __ | electrical load |
| In a __ __ the loads are connected one after the other in the ciricut path | series circuit |
| All the charges from the source flow through __ the __ in sequence at the same rate | all, loads |
| this means that the __ amount of current flows through all the loads. | same |
| if any one load is broaken the circuit is broken and the current __ _____ through all the loads. | stops flowing |
| In a ____ ____ the loads are connected in seprate _____ of the currciut. | parallel curcuit, branches |
| The current flows through more than one ___, splitting up the flow through each load. | path |
| the current running through each bulb in a _____ _____ depends on its ______ accordibng to ____ law. | parallel curciut, resistance, Ohm's |
| if the bulbs all have the same resistances, the currents are the ___ in each. | same |
| if one bulb in a parallel curciut rurned off or burns out, the curciut will _____ to flow through the other branches and the bulbs will _____ to burn. | Continue, continue |
| a current takes the path of ___ ______ ________ back to its source...... if a cords insulatuion is damaged so that two wires touch, the current will bypass the load or applience, taking a ______ where the wires touch. | least electrical resistance, shortcut |
| this condition is called a ____ ______. | short curciut. |
| if a current in the wire increases too much, the heat released can ___ the insulation and start a fire. | melt |
| ____ ______ are the most common cause of electrical fires. | Short curcuits |
| building coads require that every electrical curciut in a buildingnhave a ______ ______. | overcurrent protection |
| each ____ has a _____ ____ conected in a series relation with the load. | curcuit, curcuit breaker |
| a _____ ______ is a switch that is manually closed but that automatically trips open if the ____ flowing is too much. | curcuit breaker, current |
| older stuff have devices called ____ | fuses |
| a ____ is a metal and glass container with a thin strip of metal inside that allows current to flow from the supply to the load. | fuse |
| the _____ and _______ of the metal determine the fuse's amperage. | thickness, material |
| it only take 0.2 A of current or less to ____ your _____. | paralyze, heart. |
