Why electric field is created?
Electric fields originate from electric charges, or from time-varying magnetic fields. The electric field is defined mathematically as a vector field that associates to each point in space the (electrostatic or Coulomb) force per unit of charge exerted on an infinitesimal positive test charge at rest at that point.
What are the important uses of electricity in school?
Electricity improves education in the following ways:
- Lighting appliances enable children to study after sunset.
- Use of electrical appliances narrow the digital divide through Information communication Technologies (ICTs)
- Improved literacy rate.
- Higher enrolment rates.

What are the possible repercussions of energy poverty?
Energy inefficiency caused by poor housing quality and structural deficiencies spurs costly utility bills that are unaffordable for low-income people (86) Poor energy efficiency has been associated with an increase in household dampness (85), which is associated with worsened arthritis symptoms, dizziness, headaches.
How does energy affect development?

How does energy poverty affect the economy?
The long-run estimated coefficient of − 29.81 suggests that a 1% increase in energy poverty will decrease economic development by 29.81% in the selected South Asian countries. However, the long-run coefficient of per capita income had a positive impact on economic development at a significance level of 1%.
How poverty is linked with energy?
The link between energy and poverty is demonstrated by the fact that the poor in developing countries constitute the bulk of an estimated 2.7 billion people relying on traditional biomass for cooking and the overwhelming majority of the 1.4 billion without access to grid electricity.
Where is energy poverty?
Energy poverty is defined as lacking access to the affordable sustainable energy service. Geographically, it is unevenly distributed in developing and developed countries. In 2015, there are estimated 1.2 billion people have no access to electricity, with approximate 95% distributed in Asia and sub-Saharan Africa.
How does poverty affect development of a country?
Countries where the level of poverty is relatively large tend also to exhibit low values of human development, thus lowering the mean values of the development measures. As an indicator of extreme poverty, this poverty rate is also the yardstick for Goal 1 of the Millennium Development Goals (MDGs).
Why is poverty a concern in development?
Inequality exists between classes of people within each country, between urban and rural areas and between different parts of the world. In each case poverty is caused by a lack of access to resources and power. In South Africa the unemployed and the unskilled workers will be bigger than in developed countries.
