Training Topics:
– Ohm’s Law describing the characteristics of resistance (R), current (I) and voltage (E) and their relationship.
– Investigation of changes in total resistance when two or more resistors are connected in series or parallel.
– Measurement of the current and potential of each element in a circuit with two or more voltage sources according to Kirchhoff’s law.
– A study of the basic circuit of the Wheatston bridge, which is used for measuring resistances and in various signal detection circuits.
