5. electricity /ˌɪlɛkˈtrɪsɪti,ˌɛlɛkˈtrɪsɪti,ˌiːlɛkˈtrɪsɪti/ noun A form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current. From Oxford
6. electronics /ɪlɛkˈtrɒnɪks,ɛlɛkˈtrɒnɪks/ noun the branch of physics and technology concerned with the design of circuits using transistors and microchips, and with the behaviour and movement of electrons in a semiconductor, conductor, vacuum, or gas. From Oxford
7. It all starts with atoms Atoms are small particles and put simply, they are the basic building blocks of everything around us, whether it is our chairs, desks or even our own body. Atoms are made up of even smaller elements, called protons, electrons and neutrons. 0.00000000001 m 0.1 nanometers
8. atom /ˈatəm/ noun the smallest particle of a chemical element that can exist.

15. Ohm's Law German physicist Georg Simon Ohm stated that the electric current flowing through a metallic wire is directly proportional to the potential difference across its ends, provided its temperature remains the same.

50. Experiment (1) When using LED’s you should always use at least one resistor to avoid the LED’s burning out. To work out what resistor is needed in your circuit use the following equation: Ohm’s Law – Resistance (R) = Voltage (V) / Current (I)
51. Experiment (1) Ohm’s Law Resitance (Ohms) = (Supply voltage - LED voltage) / LED current mA) x1000 • Resistance is measured in Ohms (Ω) • Voltage is measured in volts (V) • Current is measured in amps (A)
