- Ohm's Law: V = IR (Voltage = Current × Resistance)
- Power: P = VI (Power = Voltage × Current)
- Series Circuit: Same current flows through all components, total resistance is sum of individual resistances (Rtotal = R1 + R2 + ... + Rn)
- Parallel Circuit: Same voltage across all components, total resistance is reciprocal of sum of reciprocals (1/Rtotal = 1/R1 + 1/R2 + ... + 1/Rn)
- Current (I): Measured in Amperes (A), flow of electric charge
- Voltage (V): Measured in Volts (V), potential difference
- Resistance (R): Measured in Ohms (Ω), opposition to current flow
💡 Tips to Master Electricity & Circuits
- Remember the triangle trick for Ohm's Law (V on top, I and R below).
- Use real-life examples (e.g., battery-powered toys) to visualize concepts.
- Practice identifying circuit types visually—very common in exams!
- Think of voltage as the "push" and current as the "flow" of electricity.
- In series circuits, adding more resistors increases total resistance; in parallel, it decreases.
