What is Electric voltage and Its Unit
What is voltage?

Voltage, electric potential difference, electromotive force, or “pressure” is the difference in electric potential between two points. The voltage between two points is measured in volts (V).

Voltage can be found in many places; for example, a common 9-volt battery has a voltage of 9 volts. A 120-volt wall outlet has a voltage of 120 volts. An electrocardiogram (EKG or ECG) measures the voltage between two electrodes placed on the skin.

In an electric circuit, voltage provides the force that pushes electrons through the wires and around the circuit. The amount of voltage in a circuit is determined by the type of battery or power source being used.

Short Definitions ·        It is the difference of potential between two-point charges that’s why it is also called Potential difference. ·        The force or pressure required for the flow of charges is called voltage. ·         It is the force required for the motion of electrons, so it is also called Electro-Motive Force. Formula of Voltage V = IR Where V is the voltage applied to any circuit, I is the current flowing in that circuit and R is the resistance of that circuit. Unit of Voltage In SI units, voltage is measured in volts which are denoted by V. Volt The applied voltage to any circuit is said to be 1 volt when 1-ampere current passes through a resistance of one ohm in that circuit. How Voltage is Measured The voltmeter is an electrical device, which is used to measure the voltage.

What is Solar Energy or Solar Power
Introduction The type of energy generated by the sun is called solar energy. Solar energy is radiant light and heat from the Sun that is harnessed using many technologies such as solar power to generate electricity, and solar thermal energy (including solar water heating). Solar energy is the radiant emission of electromagnetic waves by the sun. It is a form of clean, renewable, and versatile energy. Collecting, storing, and using solar energy has many advantages, especially in space travel. This is because it is a finite resource that we must learn to harness and use wisely. The nuclear fusion that takes place in the sun resulting the creation of solar energy. When the protons of hydrogen atoms violently collide in the core of the sun and a helium atom is created, thus fusion occurs.

This process is also known as a PP (proton-proton) chain reaction, which emits an excessive amount of energy. The amount of hydrogen fused by the sun is about 620 million metric tons every second in its core. Solar energy is constantly discharging away from the sun and throughout the solar system. Solar energy warms the Earth, causes the wind and the weather, and it sustains plant and animal life.

Harnessing Solar Energy

We must learn to harness and use solar energy efficiently- both as a source of power and as an element in our creation story. We currently have many ways to efficiently collect this resource, but learning how to store it is still an issue. Even though it is abundant in the universe, the earth's atmosphere contains elements that hinder solar energy. We must learn to collect and use solar energy effectively no matter how much sunlight we have access to.

Solar energy is a renewable source of energy, and it can be harvested by many technologies directly for domestic and commercial use. Some solar energy technologies contain photovoltaic cells and panels, concentrated solar energy, and solar.

There are many ways for capturing solar radiation and converting it into usable energy. The methods used may be active solar energy or passive solar energy.

Active solar technologies use electrical or mechanical components to actively convert solar energy into another form of energy, these forms are most often heat or electricity. Passive solar technologies do not use any external components. However, they take benefit of the local climate to heat structures during the winter and reflect heat during the summer.

Photovoltaics

It is a form of active solar technology that was discovered by 19-year-old French physicist Alexandre-Edmond Becquerel in 1839. Becquerel found that when he placed silver chloride in an acidic solution and brought it to sunlight, the platinum electrodes generated an electric current that was attached to it. This process of producing electricity directly from solar radiation is known as the photovoltaic effect or photovoltaics.

What is Electric Current and its Unit
Electric current definitions · The electric current is said to be the rate of flow of charges. · The rate of flow of electrons in an electric circuit is called electric current or the flow of charges per second time is called current. In general, electric current is the flow of electric charge. This charge is often carried by electrons in a metal conductor such as a wire. The charge can also be carried by ions in an electrolyte, or by both electrons and ions in a plasma. In fact, anything that can flow can carry electric current. For example, water current is the flow of water molecules through a pipe, and blood current is the flow of blood cells through a vessel. By analogy, we often speak of an "electric current" flowing through a circuit.

' The electric current in a circuit An electric current is a flow of electrons through a conductor, and it's measured in amperes. The current in a circuit is caused by a voltage difference, and it will flow if there's a complete path (a circuit) between the two points of voltage. The current is affected by the resistance in the circuit. If there's more resistance, the current will be less because it will be opposed by the resistance. If there's less resistance, the current will be greater because there will be less opposition to its flow.

 Electric Current Formula Mathematically, 1. I = V / R Where I is the current flowing through any circuit as a result of the voltage applied V, and R is the resistance of the same circuit. So, Current = Voltage / Resistance 2. I = Q / T Where Q is the charge in coulombs, which is the unit of charge and T is the time in seconds.
