A demand pump is a small pump that is activated when water is required and transports it from a storage tank to the point of usage in response. Generally, demand pumps are a simple, versatile, and cost-effective solution for controlling water flow in your home, garden, and more. For instance, when a faucet is turned on, the demand pump is operated and sends water through the open line as long as the faucet is running and consuming water. Similarly, the demand pump automatically shuts off when the faucet is turned off and the water demand has passed.

Capacitors are one of the primary components found in all electronic devices, making them vital to their operation. Modern day electronics are usually equipped with ceramic capacitors decoupling power supplies for a majority of integrated circuits (ICs) on circuit boards or aluminum electrolytic capacitors as bulk capacitance for voltage regulators. As capacitors are utilized for reasons other than noise mitigation, there are several different types of capacitors available on the market. For instance, they can be used for coupling, decoupling, as filters, energy storage/supply, impedance matching, snubbers, and more.

Resistors are electronic devices that are designed to impede the flow of current running through their bodies, allowing for the protection of sensitive electronics while also opening up the opportunity to control and manage voltage values for specific applications. As a technology that was first invented in 1959, resistors now serve almost all electrical circuits. With a variety of resistor types featuring different constructions, materials, tolerance values, and other characteristics, finding the correct type often depends on the specific needs of the operation. In this blog, we will discuss the carbon film and metal oxide film resistor in particular, allowing you to best understand the differences between two very common electrical circuit components.
