Experiments In Electrical Engineering – As Described By Faculty

What is Electrical Engineering?

Electrical engineering is a branch of engineering dealing with electricity and its applications for human use. It aims at better distribution and use of power through efficient electrical equipment and devices. Today almost every second home in the world has a reach to electricity and electrical devices. The field of electrical engineering is growing at a quick pace and has developed several specialized branches focusing on motors, batteries, power transmissions and generation systems, radio frequency (RF) systems, remote sensing, signal processing, telecommunications, audio, video and various other electronic applications.

What are the Important Experiments in Electrical Engineering?

Here an experiment in electrical engineering is described. Other experiments are mentioned for the reference of the students that these can also be provided in our electrical engineering assignment help.

Experiment No. 1: Aim: To verify Kirchhoff’s Current Law (KCL) and Kirchhoff’s Voltage Law (KVL) Apparatus required:
  • C Ammeter – 3 Nos. (0-10 amp)
  • C. Voltmeter – 3 Nos. (0-300 V)
  • Rheostat
  • Inductive Load
  • Connecting Wires
Procedure: For KCL:
  • First measure the least count of all ammeters A1, A2, A3 and all voltmeters V1, V2, V3.
  • Connect the circuit.
  • Now, vary both the resistive and inductive loads to obtain different readings of ammeters A1, A2 and A3 and voltmeters V1, V2 and V3.
  • Repeat the same procedure for different observations.
  • Calculate percentage error.
For KVL:
  • Connect the circuit.
  • Now, adjust both the rheostat and the Inductive Load to obtain different values of voltmeters V1, V2 and V3.
  • Repeat the same procedure for different observations.
  • Calculate percentage error.
Observation table:

For KCL:

S. No. V1 in (Volts) V2 in (Volts) V3 in (Volts) V1 = √V22 + V32 % error

For KVL:

S. No. A1 in (Volts) A2 in (Volts) A3 in (Volts) A1 = √A22 + A32 % error

Precautions:
  • Make the connections properly.
  • Note the readings properly.
  • Remove insulations from connecting wires for the flow of proper current.
  • Avoid loose connections and don’t touch wires with wet hands.
Other experiments are as follows: (Headings only)
  • Load test on DC Shunt & DC series motor.
  • Study of Dc and AC starters.
  • Load test on single phase Induction motor.
  • C. C. & Load characteristics of DC shunt and DC series generator.
  • Speed control of DC shunt motor (Armature & field control).
  • Speed control of three phase slip ring Induction motor.
  • Load test on single phase transformer.
  • Load test on three phase squirrel cage Induction motor.
  • C. and S. C. test on a single phase transformer.
  • V curves and inverted V curves of the synchronous motor.
  • Regulation of an alternator by EMF and MMF methods.
