  1. ELECTRIC CURRENT SOURCES Voltaic Elements A glass jar that contains H2SO4 solution Plate of platinum as a positive electrode (cathode) Plate of Zinc (Zn) as a negative electrode (Anode) The chemical reactions causes electrons from Zinc plate to flow to the platinum plate. So, if a bulb connected to these two poles, it will turn on

  2. (H2SO4)

  3. measuring ELECTRIC CURRENT An ammeter is an instrument used to mesure current that passes through a node or another part of a circuit. An ammeter to measure current is always connected in series in a circuit

  4. MEASURING POTENTIAL DIFFERENCE Voltmeter is an instrument used to measure voltage that passes across a circuit A voltmeter to measure potetial is connected in parrallel

  5. MEASURING CURRENT AND VOLTAGE MAX. VALUE SHUNT An Ameter BASICMETER UNIT + MULTEPILER SCALE SHOWN Voltmeter MAX. SCALE Reading of scale in measure: X = the scale show by the needle X the selected maximum scale the value on the scale by the max scale X = 42/60 X 20 = 14 V
