Transmitters and Receivers
Transmitters that transmit AM signals are known as AM transmitters. These transmitters are used in medium wave (MW) and short wave (SW) frequency bands for AM broadcast. The MW band… View Article Learn more

Amplitude Modulation
“Modulation is the process of superimposing a low frequency signal on a high frequency carrier signal.” OR “The process of modulation can be defined as varying the RF carrier wave… View Article Learn more
Attenuators and time constants of RC Circuit
An attenuator is an electrical network that reduces the power level of signal without appreciably distorting its waveform. Attenuators are usually resistive but also may be designed as capacitive network…. View Article Learn more
Filters
A filter is an electrical network that can transmit signals within a specified frequency range. The frequency range is called pass band and the other frequency band where the signals… View Article Learn more
Resonance
An AC circuit is said to be in resonance if it behaves in effects like a purely resistive circuit. The total current drawn by the circuit is in phase with… View Article Learn more
Resistance Capacitance and Inductance in AC Circuit
In DC, Voltage applied and current are in phase (constant with time). Calculations are simple. In AC, the voltage applied and current flowing are changing from instant to instant. The… View Article Learn more
Star Delta Transformation
Star delta transformation or Delta star transformation: It is a mathematical technique to simplify the analysis of an electrical network. Lesson 6 Learn more
Network Theorems
In complex circuits such as bridge or T networks, we can not simply use Ohm’s Law alone to find the voltages or currents circulating within the circuit. For these types… View Article Learn more
Heat
Temperature indicates the degree of heat and not the quantity of heat the substance obtained. Different temperature scales are used to represent the degree of heat. Learn more
Stress, Strain and Young’s Modulus
When a force is applied to the surfaces of a solid material, it develops a stress – a pattern of forces between the atoms in the solid. In response to a stress, the material develops a change of shape, or strain. When the stress is not too large, the strain is reversible (elastic). In this case, the relationship between stress and strain is linear: the stress is proportional to the strain Learn more
Hydraulics
Statics is the branch of classical mechanics that is concerned with the analysis of force and torque acting on a physical system that does not experience an acceleration, but rather is in equilibrium with its environment. Learn more

Dynamics
Dynamics is the branch of science that deals with the study of moving bodies. It is further divided into kinematics and kinetics. Newton formulated the laws concerning the motion of the object. Learn more
Angular Motion
Angular Motion is the motion of an object around a fixed axis or point, or along a curved path with a constant angular velocity. It is also known as rotational motion. Another motion of an object is termed linear motion, which is a motion along a straight route. Linear motion variables are measured in units of length, whereas angular motion variables are measured in angular units like radians or degrees. Learn more
Kinematics
Kinematics is the study of the motion of mechanical points, bodies and systems without consideration of their associated physical properties and the forces acting on them. The study is often referred to as the geometry of motion, and it models these motions mathematically using algebra. Learn more
