In electrical engineering, a relay is a switch that is operated by an electromagnet, while a contactor is a larger and more heavy-duty switch that is typically used for higher power applications. Relays are often used in control circuits to switch smaller loads, while contactors are used for switching larger loads such as motors or heaters.
Electrical engineering is low voltage, logic circuits, communications etc. Power engineering is electrical transmission and the like.You want EE.
Motor started will have overloads the contactor connect es line voltage.
A contactor is typically used for high-power applications and has larger contacts, while a relay is used for lower-power applications and has smaller contacts. Contactors are designed to handle higher currents and voltages than relays.
Electrical engineering deals with electrical lines, transformers, circuit breakers, power transmission , generation and distribution. Instrumentation engineering is a sub branch of electrical engg. but we can say that Instrumentation engg. is mixture of electrical, mechanical(somewhat), electronics, computer(somehow)..... Instrumentation deals with sensors, transducers, analog and digital controllers, automation etc... so main difference between Instru and Electrical is, Instru. for making plant Automatic and electrical for making plant powered with electricity ....
there is a difference
what is difference between accounts and engineering
Different universities most probably have different names for what may or may not be similar bachelor-level degrees. Without knowing which uni awards a B.Sc. in Electrical Engineering and which uni awards a B.Elec.Eng. its impossible to say what the difference is. If you wish to compare two such degrees you have to read and compare the curricula of the two degree courses which lead to those awards.
No, there is not any difference between the switching action of a relay and a contactor. Both of these devices are operated by an electro magnetic coil.
The difference between computer engineering and digital electronics is that digital electronics represents signals. Computer engineering integrates several fields of computer science and electrical engineering to make computer systems. Digital electronics is the field of computers and computer controlled devices including the ones with analog inputs and outputs.
There are several ways to differentiate it bur the most basic difference is that in electrical engineering we deal with flow of electrons, while in electronic engineering we deal with transfer of electrons(through holes).
spelling difference
Yes, there is a difference.
