Internal resistance refers to the opposition to the flow of electric current within a power source, such as a battery or a fuel cell. It occurs due to various factors, including the chemical reactions occurring inside the battery, the physical properties of the materials used in the battery, and any ionic conductivity limitations within the electrolyte. When a current flows from a power source, internal resistance causes some of the voltage to be lost as heat instead of contributing to the output voltage available to an external load.

An ohmmeter is an instrument used to measure electrical resistance in ohms (Ω). It is a fundamental tool in electronics and electrical engineering, useful for diagnosing faults in circuits, checking the integrity of components, and verifying connections. ### Key Features of an Ohmmeter: - **Resistance Measurement**: It directly measures the resistance of resistive components, such as resistors, wiring, and other electronic components.

JIS semiconductor designation refers to the classification system used by the Japanese Industrial Standards (JIS) for identifying semiconductor devices. This system helps in specifying the characteristics and attributes of semiconductors, such as diodes, transistors, and integrated circuits. The JIS designation typically includes a code that provides information about the type of device, its operating conditions, and electrical characteristics. For example, JIS may specify the maximum voltage, current ratings, and package type of the semiconductor.

Ampacity is the maximum amount of electric current (measured in amperes) that a conductor or device can carry before becoming overheated and potentially failing or causing a safety hazard. This limit is influenced by various factors, including the conductor's material (such as copper or aluminum), its cross-sectional area, the insulation type, ambient temperature, and the installation conditions (such as whether the wire is in open air or buried).

A Western Union splice is a method of joining two pieces of wire or rope together. This splice is particularly useful when connecting wires in a way that maintains electrical continuity and provides a strong mechanical connection. The basic process for a Western Union splice involves stripping the insulation off the ends of two wires and then twisting them together. Specifically, one wire is placed on top of the other, and the exposed ends are twisted around each other in a manner that creates a secure connection.
