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 […]
Resistance Resistance is the measurement of the ability of electrons to move through a material. A copper wire with a large diameter has lower resistance to the flow of electrons than a copper wire with a small diameter. You need to understand resistance because almost every electronics project you do involves a resistor. Resistors have
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

Semiconductors and Alarm Systems Describes solid-state components. Often used when discussing transistors, which are commonly made of silicon. They can function as an insulator or a conductor dependent on changes in voltage. They are excellent switching devices, have no moving parts, able to change between conductive and nonconductive state very quickly. Semiconductors in their natural state, are neither
Insulators: How They Protect Electrical Circuits and Alarm System Wiring Insulators are materials that do not conduct electricity and are used to separate electrical components and keep the flow of current along the intended path. Insulators play a crucial role in maintaining the safety of electrical systems, as they prevent accidental contact with live electrical
Conductors: How Electrical Conductors Work in Alarm Systems A conductor is a material that allows electricity to flow through it with minimal resistance. This means that electrons can move freely within the material, making it possible for an electric current to be established. Conductors are essential in electrical circuits as they provide a path for
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
Welcome to Basic Electronics “Basic Electronics” refers to the study and application of electrical systems and circuits. It encompasses the fundamental principles of electricity and electronics, including the behavior and manipulation of electrons and their interactions with different components such as resistors, capacitors, and transistors. This knowledge is applied in a wide range of fields,
