Current surges are sudden increases in current caused by voltage imbalances. They can be internally generated by capacitor surge current or externally generated by lightning strikes. Surge protectors are available for all types of signals, and predicting peak current is important for building reliable equipment. A current surge is a sudden increase in current usually […]
A current sensor measures the flow of electric current on a power line by measuring the voltage drop across a resistor. It can be used for performance monitoring, protection against overcurrents, and battery charging. There are two approaches to current sensing: low side detection and high side detection. A current sensor is an electrical device […]
Present weather is the atmospheric condition at a given moment, affected by solar radiation and the Earth’s tilt. The jet stream and small atmospheric changes can impact weather globally. Other planets also experience weather changes, with Venus and Jupiter having notable phenomena. The present weather is the condition of atmospheric phenomena occurring at a given […]
Current sources produce or receive electric current and come in various types, including resistor, active, RF, DC, and AC sources. Resistor sources are simple but not efficient, while active sources use transistor elements or vacuum tubes to replace the resistor. DC and AC sources are used in different processes, and RF sources operate at a […]
Eddy currents are generated when two electromagnetic fields cross, creating resistance and converting electrical energy into heat. They can be used for identifying metals, braking railroad cars, and non-destructive analysis of conductive metals. In transformers, special construction is required to prevent eddy currents from impeding the primary electric force. NASA uses eddy current inspection for […]
Inrush current is a surge of energy that occurs when an electronic or magnetic device is turned on, which can cause damage to the device or blow fuses and circuit breakers. Thermistors and active circuits are built into devices to compensate for the large inrush current. Surge protectors can also be installed to limit the […]
CPT is a set of codes used for medical procedures in the US, licensed by the American Medical Association. It is used to describe medical treatments and practices and is divided into three categories. Category I is used for vaccines, Category II for standard treatments, and Category III for emerging technologies. CPT may also describe […]
A current situation analysis is a concise review of a company’s market position, including macroeconomic trends, customer data, and competitor information. The SWOT method is often used to analyze data and identify strengths, weaknesses, opportunities, and threats. This analysis helps predict future performance and progression. A current situation analysis is a clear and concise look […]
A mortgage is when a lender is given an interest in real property as security on a loan. Interest is charged on the amount borrowed, and current rates vary based on loan terms and creditworthiness. High credit scores can result in rates in the 5% range, while low scores can result in rates between 9% […]
Current best practice (BCP) is a widely accepted method for drafting guidance documents, subject to change as best practices develop. It is used in various businesses and has a specific meaning in the IT community. The Internet Engineering Task Force uses BCP documents to recommend the most effective way to perform various Internet and networking-related […]
The charging current is used to recharge reusable batteries by converting chemicals into stored electricity. Lead-acid batteries can suffer from sulfation, but pulse charging can help restore them. Charging current should be regulated to prevent overheating. Nickel metal hydride and lithium ion batteries require separate charging. Capacitors can also be charged and used in electronics. […]
Electricity and magnetism are interconnected, with a flow of electrons in a wire producing a magnetic field. Induced current can be amplified through a tight coil or transformer, and electromagnets can attract or repel each other. A closed electrical circuit with energy flow illustrates the two parts of the electromagnetic force: electricity and magnetism. Electricity […]
Magnetic currents are energy waves that can produce heat and energy. Professor Felix Ehrenhaft’s experiments showed that magnetic currents can break water and release oxygen and hydrogen. Magnetic currents have potential as a rival to electric currents, but more research is needed to determine their behavior and how they can be harnessed. Like electric current, […]
Current portion of long-term debt is the amount of long-term debt obligations that must be paid off within the next twelve-month period, and is an ongoing process that is often updated monthly. It is important to maintain this accounting process to compare the long-term debt with current cash and cash equivalents, and to avoid damaging […]
Current dollar GDP is the most recent estimate of Gross Domestic Product (GDP) in terms of current year dollars, but comparing it to nominal GDP of other years doesn’t account for inflation. Real GDP takes inflation changes into account, allowing for a true comparison of GDP between years. Knowing current GDP in dollars can still […]
A checking account is a statement given to insurance sales agents to show their commission earned, with information on policies sold, premiums paid, and other relevant data. Brokers may also receive a similar statement, and individual workers may receive reimbursements for business use of personal assets. A checking account is a statement given to individual […]
Financial firms use indices to track average yields on securities and interest rates on loans. Mortgage rates are compared to government bond yields, with mortgage rates set higher due to higher risk. Variable rate loans and deposit products are also affected by index values. Economists use indices to predict housing market activity and overall economic […]
Current portion of long-term debt is the amount of long-term debt that must be paid within the next 12 months. Companies use accounting practices to simplify budget preparation and ensure timely payment to avoid damaging credit ratings. Long-term debt is segregated into long-term and short-term debt on the balance sheet. Maintaining this accounting process helps […]
