How Batteries work Batteries power everything from small electronics to alarm systems. Understanding how they work helps you choose the right type and avoid common mistakes. A battery has two terminals, a + positive terminal, and a – negative terminal. Different sizes and shapes can be constructed using cells, so their sizes and shapes can […]

Current Flow Electron theory helps to explain electricity. Conventional theory (+ to -) and electron theory (- to +) both describe the flow of electrons, however conventional theory states that current flows from positive to negative, while electron theory states that current flows from negative to positive. The use of conventional theory in calculations is
Ohms Law The relationship between Voltage, Current and Resistance is known as Ohm’s Law. So, when we work with alarm systems, we use the values to multiply and divide to calculate resistance values ect. So, to convert between different units of measurement, we use the prefixes kilo, milli, and micro to represent multiples or fractions
Current CURRENT (AMPERES). CURRENT is the quantity or flow rate of electrons moving past a point within one second. Current flow is also known as amperage, or amps for short. Higher voltage will produce higher current flow, and lower voltage will produce lower current flow Flow rate of electrons moving past a point in seconds. Neo
Voltage The previous sections explain how electrons move and that they move more freely in a conductor. But some kind of force has to pull the electrons from one place to another. This attractive force between positive and negative charges is an electromotive force called voltage. Negative electrons move toward a positive voltage by way
Voltage, Current and Resistance for Alarm Systems In Alarm Systems, voltage is an important aspect to consider when designing and installing the system. The voltage supply is by design (12Vdc/13.5Vdc) and is used to power the various components of the alarm system, including sensors, control panels, and other electronic devices. For Alarm systems, they use voltage

What is Electricity: A beginner’s guide Like most things in life, electricity is more complex than you might think. A lot of conditions have to be just right and come together to make that little spark when you touch a car door or provide power to a small single board computer. To understand how electricity
