EEE Projects Ideas for Final Year Students

EEE projects ideas

EEE projects ideas EEE refers to Electrical and Electronics Engineering. Nowadays most of the students showing interest to join in this branch to complete their B.Tech successfully and to build good career in future. In EEE, they can learn different concepts on electronics and complete their project in final year. Many of them try to do creative and innovative projects. Some of them also try to do the projects which may be helpful in real life.

For their purpose, here we have listed few best projects ideas from various categories like embedded, electrical, robotics, DTMF, GSM, RF, RFID, etc. Most of these EEE projects ideas give a better idea in electronic circuits and their functionality. These ideas are collected from different sources for the convenience of EEE students. We hope these EEE projects ideas are very useful for engineering students in completing their B.Tech successfully.


Current is the flow of charge.

Charge flows in a current.

Current is reported as the number of charges per unit time passing through a boundary. Visualize placing a boundary all the way through a wire. Station yourself near the boundary and count the number of charges passing by. Report how much charge passed through the boundary in one second. We assign a positive sign to current corresponding to the direction a positive charge would be moving.

A few remarks on current

What carries current in metal? Since electrons are free to move about in metals, moving electrons are what makes up the current in metals. The positive nuclei in metal atoms are fixed in place and do not contribute to current. Even though electrons have a negative charge and do almost all the work in most electric circuits, we still define a positive current as the direction a positive charge would move. This is a very old historical convention.
Can current be carried by positive charges? Yes. There are lots of examples. Current is carried by both positive and negative charges in saltwater: If we put ordinary table salt in water, it becomes a good conductor. Table salt is sodium chloride, NaCl. The salt dissolves in water, into free-floating Nastart superscript, plus, end superscript and Clstart superscript, minus, end superscript ions. Both ions respond to electric force and move through the saltwater solution, in opposite directions. In this case, the current is composed of moving atoms, both positive and negative ions, not just loose electrons. Inside our bodies, electrical currents are moving ions, both positive and negative. The same definition of current works: count the number of charges passing by in a fixed amount of time.
What causes current? Charged objects move in response to electric and magnetic forces. These forces come from electric and magnetic fields, which in turn come from the position and motion of other charges.
What is the speed of current? We don’t talk very often about the speed of current. Answering the question, “How fast is the current flowing?” requires understanding of a complex physical phenomenon and is not often relevant. Current usually isn’t about meters per second, it’s about charge per second. More often, we answer the question “How much current is flowing?” all the time.
How do we talk about current? When discussing current, terms like throughand in make a lot of sense. Current flows through a resistor; current flows in a wire. If you hear, “the current across …”, it should sound odd.


To get our initial toehold on the concept of voltage, let’s look at an analogy:

Voltage resembles gravity

For a mass m, a change of height h corresponds to a change in potential energy, delta, U, equals, m, g, delta, h.
For a charged particle q, a voltage V corresponds to a change in potential energy, delta, U, equals, q, V.
Voltage in an electric circuit is analogous to the product of g, dot, delta, h. Where g is the acceleration due to gravity and delta, h is the change of height.
A ball at the top of the hill rolls down. When it is halfway down, it has given up half of its potential energy.
An electron at the top of a voltage “hill” travels “downhill” through wires and elements of a circuit. It gives up its potential energy, doing work along the way. When the electron is halfway down the hill, it has given up, or “dropped”, half of its potential energy.
For both the ball and the electron, the trip down the hill happens spontaneously. The ball and electron move towards a lower energy state all by themselves. On the trip down, there can be things in the way of the ball, like trees or bears to bounce off. For electrons, we can guide electrons using wires and make them flow through electronic components —circuit design— and do interesting things along the way.
