Electricity — Key Formulas
| Formula | Expression |
|---|---|
| Electric current definition | I = Q/t; unit = Ampere (A); flow of charge per unit time |
| Ohm's law | V = IR; resistance R = V/I; unit = Ohm (Ω) |
| Resistivity | R = ρL/A; ρ = resistivity, L = length, A = cross-section area |
| Series resistance | R_total = R₁ + R₂ + ... (same current, V divides) |
| Parallel resistance | 1/R_total = 1/R₁ + 1/R₂ + ... (same V, I divides) |
| Power of electric current | P = VI = I²R = V²/R; unit = Watt (W) |
| Joule's heating law | H = I²Rt; heat produced in resistor |
