Series vs parallel circuits
串联电路与并联电路
Description
Describe and apply the rules for current, voltage, and resistance in series and parallel circuits, and explain the practical uses of each circuit type
Mastery Evidence
- States the rules for current and voltage in series circuits (current same everywhere; voltages add up)
- States the rules for current and voltage in parallel circuits (voltages same across each branch; currents add up)
- Explains why household wiring uses parallel circuits and identifies the advantage of each type
Assessment Prompt
Can your child explain why the lights in your home don't all switch off when you turn off one room's light, but a string of old-fashioned Christmas lights does go off if one bulb breaks?
