1 use these to convert to the standard unit 2 ie: 3 1km = 1 x 1000 meter 4 1mV = 1 / 1000 volts 5 6 G = giga = x 1,000,000,000 = x10^9 7 M = mega = x 1,000,000 = x10^6 8 k = kilo = x 1000 = x10^3 9 m = milli = / 1000 = x10^-3 10 u (funny u (mu)) = micro = / 1,000,000 = x10^-6 11 n = nano = / 1,000,000,000 = x10^-9 12 p = pico = / 1,000,000,000,000 = x10^-12 13 14 you can do the inverse of those to convert to a more reasonable scale 15 ie: 16 120,000V = 12kV 17 0.15A = 150mA 18 19 first half of the lesson was learning those and touching up on standard form 20 21 second half we are going over current and voltage 22 23 current is the rate of flow of charge, to find the current, i = q/t with i being current, q is culombs and t is time 24 AMETERS GO IN SERIS 25 26 voltage is the energy tranfered per unit of charge 27 v = e/q with v being volts, e being energy, and q being culombs 28 VOLTMETER GO IN PARRALEL 29 30 later on we are doing practical, mesuring voltage with circuit with a bulb or a resistor 31 plotted the results on a graph, my resistor graph was perfectly liner 32 and my bulb graph is more similar to a cubic graph 33 - 34 / 35 - 36 kind of like that 37 38 we looked at a bit of resistance at the end, worksheet work (BRING IT TO THE NEXT LESSON)
