What is the main characteristic of a series circuit?
Components are connected side by side
Voltage is the same across all components
Components can be disconnected without affecting others
Current is the same throughout
In a parallel circuit, if one component fails, what happens to the rest of the circuit?
Current stops flowing
Only the failed component is affected
All components fail
Voltage increases
How do you calculate the total resistance in a series circuit?
Add all resistances together
Use the formula 1 / 𝑅 𝑡 𝑜 𝑡 𝑎 𝑙 = 1 / 𝑅 1 + 1 / 𝑅 2
Take the average of the resistances
Use Ohm's Law
