To equip the students to apply all types of common electrical and electronic instruments with
the knowledge about the construction and working of the instruments.
To provide the details of various electronic instruments which are used to measure current,
voltage, power, energy, resistance, capacitance and inductance.
To introduce the construction and working of different types of ammeters, voltmeters and
bridges.
A clear idea has been given about digital electronic instruments which are used to measure
voltage, frequency, period, total count etc.
An exposure is given to the student about signal generation, display and recording devices
which help in analysing and displaying the data.
