Comparison of JFET's and MOSFET's:

• JFET's can only be operated in the depletion mode whereas MOSFET's can be operated in either depletion or in enhancement mode. In a JFET, if the gate is forward-biased, excess-carrier injunction occurs and the gate-current is substantial.

• MOSFET's have input impedance much higher than that of JFET's. Thus is due to negligible small leakage current.

• JFET's have characteristic curves more flat than that of MOSFET is indicating a higher drain resistance.

• When JFET is operated with a reverse-bias on the junction, the gate-current IG is larger than it would be in a comparable MOSFET.

Employer will want to know if you have the right skills and credentials for the job. Mention your education, any relevant certifications, and experience from previous jobs that specifically pertain to an electrician's job.

Differential Amplifier: The amplifier, which is used to amplify the voltage difference between two input-lines neither of which is grounded, is called differential amplifier. This reduces the amount of noise injected into the amplifier, because any noise appearing simultaneously on both the input-terminals as the amplifying circuitry rejects it being a common mode signal.

CMRR: It can be defined as the ratio of differential voltage-gain to common made voltage gain. If a differential amplifier is perfect, CMRR would be infinite because in that case common mode voltage gain would be zero.

Cables, which are used for transmitting power, can be categorized in three forms:

☛ Low-tension cables, which can transmit voltage upto 1000 volts.

☛ High-tension cables can transmit voltage upto 23000 volts.

☛ Super tension cables can transmit voltage 66 kV to 132 kV.

Power engineering is a sub division of electrical engineering. It deals with generation, transmission and distribution of energy in electrical form. Design of all power equipments also comes under power engineering. Power engineers may work on the design and maintenance of the power grid i.e. called on grid systems and they might work on off grid systems that are not connected to the system.

Storage batteries are used for various purposes, some of the applications are mentioned below:

• For the operation of protective devices and for emergency lighting at generating stations and substations.

• For starting, ignition and lighting of automobiles, aircrafts etc.

• For lighting on steam and diesel railways trains.

• As a supply power source in telephone exchange, laboratories and broad casting stations.

• For emergency lighting at hospitals, banks, rural areas where electricity supplies are not possible.

According to thevenin's theorem, the current flowing through a load resistance

Connected across any two terminals of a linear active bilateral network is the ratio open circuit voltage (i.e. the voltage across the two terminals when RL is removed) and sum of load resistance and internal resistance of the network. It is given by Voc / (Ri + RL).

Star delta starter is preferred with induction motor due to following reasons:

• Starting current is reduced 3-4 times of the direct current due to which voltage drops and hence it causes less losses.

• Star delta starter circuit comes in circuit first during starting of motor, which reduces voltage 3 times, that is why current also reduces up to 3 times and hence less motor burning is caused.

• In addition, starting torque is increased and it prevents the damage of motor winding.

If you are currently employed and are seeking a job, then you will probably hear this question. Be honest, but be careful to say anything that might indicate that you may have problems getting along with your coworkers. Don't make negative comments about particular individuals or indicate personality problems with coworkers. Focus on work-related reasons for leaving.

The Norton's theorem explains the fact that there are two terminals and they are as follows:

• One is terminal active network containing voltage sources

• Another is the resistance that is viewed from the output terminals. The output terminals are equivalent to the constant source of current and it allows giving the parallel resistance.

The Norton's theorem also explains about the constant current that is equal to the current of the short circuit placed across the terminals. The parallel resistance of the network can be viewed from the open circuit terminals when all the voltage and current sources are removed and replaced by the internal resistance.

Few advantages of storage batteries are mentioned below:

• Most efficient form of storing energy portably.

• Stored energy is available immediately because there is no lag of time for delivering the stored energy.

• Reliable source for supply of energy.

• The energy can be drawn at a fairly constant rate.

Employers are looking for steady work employment and not short term assignments and big gaps between jobs. You should be prepared to explain any gaps between jobs. Another piece of advice is to focus on work experience relevant to the position you are currently applying for as well as your most recent work history.

Depending on they type of job you are interviewing for, either industrial, residential or commercial, you might be asked why you are interested in that field and not one of the others.
