Magnetic_Field_Lines

In this blog, we will review the theory of Magnetic Fields and its basic concept. We all know that magnets exert forces on each other and its magnetic force is distributed around. Magnetic field lines are used to describe these forces around the magnet. We understand that magnets have two poles and that depending on the orientation of two magnets there can be an attraction (opposite poles) or repulsion (similar poles).

Air Gap

In this blog we will review the theory of the Air gaps in magnetic circuits. A magnetic circuit is where a magnetic flux is circulated or follow through a closed area or path. An air gap is a non-magnetic part of a magnetic circuits and it is usually connected magnetically in series with the rest of the circuit. This allows a substantial part of the magnetic flux flows through the gap.

Divider Circuits

In this blog we will review the theory of the Current Divider circuits in a parallel circuit. In a parallel circuit, all the components have their terminals connected together sharing the same two end nodes. This results in different paths and branches for the current to flow or pass along. However, the currents can have different values through each component but the voltage remains the same across two end nodes.

DC supply with a switch and a coil

In this blog we will explore Inductance; one of the major properties of an electrical circuit or an electronic device. Inductance is defined as a property of electrical circuit or a device that opposes a change in current. It is important to note that inductance does not oppose the current but rather opposes the change in current flowing within the circuit.

electric circuit filters speakers

In electronics, filters serve a critical role in many common applications such as audio electronics, radio communications and power supplies. We use filters to block or pass a specific range of frequencies. The filters can be either passive or active.  We usually divide filters into four main types, depending on which frequency components of the input signal they pass on to the output signal. Read More
