HISTORY OF ELECTRICITY• The first knowledge about electricity existed people were aware of shocks from electric fish.Picture 1: Cat Fish Picture 2: Electric Eel
HISTORY OF ELECTRICITY• In 1600, William Gilbert made a study of electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing amber• The name of “electric” and “electricity” was taken from the New Latin word electricus, "of amber" or "like amber" from Greek word to refer to the property of attracting small objects after being rubbed.
HISTORY OF ELECTRICITY• Electricity and magnetism were definitively linked by James Clerk Maxwell, in particular in his "On Physical Lines of Force" in 1861 and 1862.
PRODUCING ELECTRIC• Lenz law: The electic current is produce by changing the mgnetic flux. Picture 3: The mechanics in Lenz Law
SPINNER MODIFICATION READY MADE MODIFICATION The speaker magnetThere is no magnet on the was placed on the original spinner in the AC spinner
MAGNET FERRITE MAGNET NEODYMIUM SILVER EARTH MAGNETS• Not suitable for high weight motor • Strong magnet• Weaker magnet only • More suitable for the high suitable for small motor motor Whiteboard magnet that we Speaker magnet that weobtained from CCY bookstore. obtained from scrap metal shop Tg.

RESULT Induced Current, Voltage and Resistance trial Induced Voltage (V) Resistance (Ω) current(A) 1 2.76 2.21 0.8 2 2.80 2.24 0.8 3 2.51 2.01 0.8Average voltage = (2.01 V + 2.24V + 2.21V )/ 3 = 2.15 V
trial Total distance Time taken (s) Velocity (m/s) (m) 1 1.0 2.4 0.48 2 1.0 2.2 0.45 3 1.0 2.4 0.48Average Velocity of water = (0.48 m/s + 0.45 m/s + 0.48 m/s ) / 3 = 0.47 m/s
Volumetric flow rate (V) = (π/4) X (pipe diameter )2 X velocity of waterThus, Volumetric rate flow(V) = (π/4) X (diameter of hole on turbine that trap river water )2 X velocity of water Thus, Volumetric rate flow(V) = (π/4) X (0.15 m) 2 X 0.47 m/s = 0.0083056 cubic meter per second
Power (P) = HpVWhere, P = power in watt H = height of water p = density of water V = volumetric flow rate in cubic meterpower (P) = (0.103 m) ( 1 g/m3) (0.0083056m3/s) = 0.000855476 watt
