Short circuit: A short circuit occurs when an electrical current deviates from its normal path, typically due to a fault in the wiring or a component failure. This causes a large amount of electrical current to flow, which can cause damage to the wiring, components and appliances. Overloading: Overloading occurs when the electrical power being …

Parallel connection is a type of connection that allows multiple devices to be connected at the same time. It is used for connecting devices with large data transfer requirements, such as printers and scanners. Parallel connections are more reliable than serial connections, but they are also more expensive and can be more difficult to set …
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 …
