Electric Energy: Consumption and Conservation

4 entries
1 unit = 1 kWh = 3.6 × 10⁶ J
For electrical appliances: P = I²R = V²/R = VI.
Electrical energy consumed = Power × Time.
Commercial unit is kilowatt-hour (kWh) or 'unit'. 1 kWh = 1000 Wh = 3.6 × 10⁶ J.

Lenses

3 entries
1/f = 1/v - 1/u, where f = focal length, v = image distance, u = object distance.
Alternative form: f = uv/(u+v).
m = hi/ho = v/u, where hi = image height, ho = object height.

Mechanical Advantage in Action

5 entries
Principle of lever: Load × Load arm = Effort × Effort arm
Fixed pulley: MA = 1, changes direction of force only
Movable pulley: MA = 2, reduces effort by half but doubles distance
MA = R/r (R = wheel radius, r = axle radius)
MA = Load/Effort.
