Series connection is a type of electrical connection in which the components are arranged in a single loop, so that the current flows through each component in turn. It is in contrast to parallel connections, in which the components are arranged side by side, so that each component is connected directly to the source.
The arrangement of resistors in circuits depends on the type of circuit being constructed. Generally, resistors are connected in series or parallel to control the current flow in a circuit. In series, each resistor is placed in line with the other, so that the current must pass through each resistor in succession. In parallel, each …

Joule’s law, also known as the Joule-Thomson effect, states that when a gas is allowed to expand through a porous plug or orifice, the temperature of the gas will decrease. This effect is due to the fact that the expanding gas does work against the external pressure, and the energy required to do this work …
The heat effect of electric current is the amount of heat generated when electric current passes through a resistance. This heat is generated due to the resistance of the material to the flow of electric current, and is measured in joules per coulomb, or J/C. The heat generated by a current is proportional to the …

Algae and phytoplankton are microscopic aquatic plants that are the basis of the food web in the aquatic environment. Algae are generally larger than phytoplankton and often form visible blooms on the water’s surface. Algae are found in both fresh and saltwater environments and can range from simple single-celled organisms to complex multicellular forms. Phytoplankton …

Animals obtain various types of nutrients from plants in the form of carbohydrates, proteins, lipids, vitamins, minerals, and trace elements. Carbohydrates are obtained from various sources such as grains, fruits, and vegetables. Proteins are obtained from plant sources such as legumes, nuts, and seeds. Lipids are obtained from plant oils, nuts, and seeds. Vitamins and …
Chemosynthesis is a process by which some organisms, such as certain bacteria, use chemical energy to produce organic compounds (usually sugars or other types of organic molecules), such as carbohydrates, from inorganic molecules, such as carbon dioxide or methane. This process does not involve the use of sunlight as an energy source, unlike photosynthesis.
Photosynthesis is a chemical process that occurs in plants and other organisms, in which light energy is converted into chemical energy. This chemical energy is stored in the form of sugar molecules, such as glucose. Photosynthesis occurs when water and carbon dioxide are combined in the presence of light and the enzyme, chlorophyll. The light …
