Acquisition of basic knowledge about the work in laboratory for electrical measurements.

Student should use the acquired knowledge in further education. The student will learn to work in the lab. Gaining basic knowledge of experimental work.

Measurement, Metrology, Quantities and units, systems and units, SI. Standards and common instruments. Measuring Sources: Sources of direct current / voltage, sources of AC current / voltage, variable transformers, function generators, frequency synthesizers, calibrators. Analog instruments: ammeters / voltmeters, universal instruments, wattmeters, oscilloscopes. Digital instruments: counter / timer / frequency meters, multimeters, oscilloscopes. Sensors and transducers. Auxiliary equipment: rheostats, potentiometers,decade boxes of resistance, capacitance and inductance. Virtual instruments. Distant laboratories. Serial, parallel and equivalent networks. Linear potentiometer and a fixed source. Logarithmic potentiometer and a fixed source. Determination of internal resistance of the real voltage source.
