Explanation :

A hydroelectric dam is used to produce electricity. The transformation of energy that is associated with a hydroelectric dam is :

Since the water is falling from a height so at that point the potential energy of water converts into kinetic energy. The turbine attached is used to convert the energy in the water to mechanical energy.

Finally, the mechanical energy is converted to electrical energy with the help of a generator.    

Hence, the correct option is (B) " gravitational potential energy into kinetic energy into mechanical energy into electrical energy ".

Answer:

Advantages of Hydroelectric Energy

1 Renewable

Hydroelectric energy is renewable. This means that we cannot use up. However, there’s only a limited number of suitable reservoirs where hydroelectric power plants can be built and even less places where such projects are profitable.

2 Green

Generating electricity with hydro energy is not polluting itself. The only pollution occurs during the construction of these massive power plants.

3 Reliable

Hydroelectricity is very reliable energy. There are very little fluctuations in terms of the electric power that is being by the plants, unless a different output is desired. Countries that have large resources of hydropower use hydroelectricity as a base load energy source. As long as there is water in the magazines electricity can be generated.

4 Flexible

As previously mentioned, adjusting water flow and output of electricity is easy. At times where power consumption is low, water flow is reduced and the magazine levels are being conserved for times when the power consumption is high.

5 Safe

Compared to among others fossil fuels and nuclear energy, hydroelectricity is much safer. There is no fuel involved (other than water that is).

A step-up transformer has a primary coil with 100 loops and a secondary coil with 1,500 loops. If the primary coil is supplied w
djyliett [7]

(a) The voltage that is produced in the secondary circuit is 1,800 V.

(b) The current that flows in the secondary circuit is 1 A.

<h3>Voltage in the secondary coil</h3>

Np/Ns = Vp/Vs

where;

  • Np is number of turns in primary coil
  • Ns is number of turns in secondary coil
  • Vp is voltage in primary coil
  • Vs is voltage in secondary coil

100/1500 = 120/Vs

Vs = (120 x 1500)/100

Vs = 1,800 V

<h3>Current in the secondary coil</h3>

Is/Ip = Vp/Vs

where;

  • Is is secondary current
  • Ip is primary current

Is = (IpVp)/Vs

Is = (15 x 120)/1800

Is = 1 A

Thus, the voltage that is produced in the secondary circuit is 1,800 V.
