Study Notes
Ohm's Law and Electrical Circuits
- Ohm's law states voltage is directly proportional to current and resistance
- The formula for Ohm's law is V = IR
- The SI unit of resistance is ohms (Ω)
- In series circuits, resistors share a single connection point
- Total resistance in a series circuit is the sum of individual resistances
- Example: If R1 = 10Ω, R2 = 30Ω, and R3 = 40Ω, then the total resistance (RT) is 80Ω (10 + 30 + 40 = 80)
