⚡ Voltage Rules in Circuits
In SERIES circuits:
- Voltages ADD UP: Vtotal = V₁ + V₂ + V₃
- Energy given by battery = energy taken by all components
- More resistance → larger share of voltage
In PARALLEL circuits:
- Voltage is the SAME across each branch
- Each branch connects directly to the supply
- V₁ = V₂ = V₃ = Vsupply
