Physics - Electricity - Circuits - Electrical power and energy - Electrical Power and Energy

A 5-step lesson. Step 1: 'Electrical Power: P = IV (Power = Current × Voltage). Power is the rate of energy transfer. Units: Watts (W). A 60W bulb transfers 60 Joules of energy per second.' Step 2: 'Alternative formulas (using V=IR): P = IV = I²R = V²/R. Use whichever matches what you know.' Step 3:
