• Unit of electromotive force in Volt.
• Power is measured in Watts (w).
• Resistance was discovered by Girge Ohm in 1826, and is measured in ohms.
• Electricity does not flow through a circuit by itself. It needs a ‘push’, or energy, to keep it moving. We call this energy the voltage of the circuit. Voltage is measured in volts (v).
• The German scientist George Ohm (1787-1854) is best remembered for working out ohm’s law. He discovered that they voltage across a conductor such as a trip of metal or a wire – and the current following through it always vary in the same proportion. So if you double the voltage, you double the current. This is incredibly useful; because it lets you predict the current you will get for a particular voltage.
• The thickness of silk is measured in what- Denier
• Ohm’s law does not apply to semiconductors and conductors when there is change in temperature.
• In our houses we get 220 V a.c. The value of 220 V represents the effective voltage.
• One unit of electric power is consumed when 10 A of current flows for 1 hour at 100 V. 1 Unit = 1 kw hr = 1000 w hr = 100 x 10 x 1 hr
