Wattage measures power consumption of electric devices. Wattage equals voltage multiplied by amperage (V x A = W). Watt became SI unit in 1960, named after James Watt
Born in 1789 in Erlangen to a Protestant family. Received excellent education from his father in mathematics and physics. Studied at Erlangen Gymnasium from age 11 to 15
Electric current is the flow of charged particles through conductors. Current is measured in amperes (A) and represented by symbol I. Current can be measured using ammeters or other devices
1 ohm equals 0.001 kiloohm. Conversion formula: kiloohms = ohms ÷ 1,000. Kiloohm is a multiple of ohm (10³)
1 ampere equals 1,000 milliamperes. Conversion formula: milliamperes = amperes × 1,000
Electric potential is work done per unit charge to move charge from infinity. SI unit is Voltage (Volt). Electric potential is a scalar quantity. Electric potential at point (Vx) is independent of charge's path
