What are the disadvantages of electric generator?
Requires very large space to collect sufficient energy.
What are the disadvantages of an ac motor?
The disadvantages of ac motor include the following.
- The starting torque of this motor is very less.
- At low speeds, it won’t operate.
- Poor positioning control.
- Limited speed through the frequency supply.
What are the disadvantages of ac and DC?
First disadvantage is that the shock of the ac is attractive but the shock of dc is repulsive. At high voltages, it is more dangerous to work with ac than dc. In the processes like electrorefining, electroplating etc. , one can not use the ac. In these processes, only dc is used.
Why are AC generators important?
The ac generator allows the user to convert the current to another voltage using a transformer. In fact, transformers are compatible with ac, but not with dc. There is a higher level of insulation due to the massive voltages required to supply a fixed amount of power from an ac motor.
What is the main disadvantage of Series generators?
The main disadvantage of series generators, Output voltage varies as the load varies The e. mf induced in the armature winding is constant with . time Inter pole winding is connected in series with main poles of d.c machine Series motor maintains a more constant speed under varying load.
What are the advantages of AC generator over DC generator?
AC can be generated at high voltages, but DC cannot be generated at high voltages because sparking starts at the commutator at high voltage, due to which commutator gets damaged. High voltages AC generators are much simpler and cheaper than DC generators of the same range.
What are the uses of AC generator?
AC generators are used in power plants, electric scooters, sailboats, bicycles, and so on. The input to the AC generators is usually mechanical energy which is supplied by steam and gas turbines & internal combustion engines.
What are the applications of AC generator?
Ans: The Uses of AC Generators are a Pervasive Component in Many Applications Such as,
- In automobiles, where they are known as alternators.
- power generation from windmills.
- power generation from hydro-electric dams.
What is advantage and disadvantage of AC?
(i) The generation of AC is cheaper than that of DC. (ii) When AC is supplied at higher voltages, the transmission losses are small compared to DC transmission. (iii) AC can easily be converted into DC with the help of rectifiers.
What are the advantages and disadvantages of AC power?
AC power has won over the DC power due to some advantages In ac power voltage levels can be transformed, thus electrical power can be generated at low voltage and step up for transmission for long distances to reduce I2R losses and can be step down at distribution end. AC generators are much simpler than DC generators.
What are the disadvantages of a power storage capacity generator?
Power storage capacity Generator can not retain power and it is the biggest disadvantage of this power producing machine. It is only produce energy when you start this machine. It also has problem of matching with voltage.
What are the disadvantages of AC power?
Critics of AC power comment on the use of inverters to transform electricity from batteries into AC when used in home power systems. They say that this is added expense and can be costly. Apart from this, there are also the wastes associated with converted energy that can be between 5\% and 15\%.
Why shouldn’t you use alternating current in a generator?
People who are not in favor of Alternating Current argue that high voltages that are essential to supply fixed power supply from AC require increased insulation, which in turn, increase the difficulty of handling it safely. This makes it more dangerous to work with AC than DC. 3. AC Generator Issues
Why do AC generators produce the wrong kind of electricity?
For the easy conversion of AC into varied voltages, AC needs to run electrons back and forth. This causes the rising and falling of magnetic fields and in order to achieve this, much power is needed. However, AC generators generate the wrong kind of electricity.
