The movement of electric charge drives the current in a circuit. The negatively charged atom-containing particles known as electrons are responsible for carrying electric charge. A power source, like a battery or generator, in a...
All atoms consist of protons, neutrons and electrons. The protons, which have positive electrical charges, and the neutrons, which have no electrical charge, are contained within the nucleus. Removed from the nucleus are minute...
Symbols are used for components in electrical circuit diagrams and some of the more common ones are shown in Fig. Read More Topics Electrical / electronic system block diagram Electrical potential and...
An electrical / electronic system is a group of components connected together to perform a desired function. Figure shows a simple public address system, where a microphone is used to collect acoustic energy in the form of sound...
When a direct current of I amperes is flowing in an electric circuit and the voltage across the circuit is V volts, then power, in watts P =VI Electrical energy = Power × time = VIt joules Although the unit of energy is the...
The unit of electric resistance is the ohm(Ω), where one ohm is one volt per ampere. It is defined as the resistance between two points in a conductor when a constant electric potential of one volt applied at the two points...
The unit of electric potential is the volt (V), where one volt is one joule per coulomb. One volt is defined as the difference in potential between two points in a conductor which, when carrying a current of one ampere...
End effectors require power to operate. They also require control signals to regulate their operation. The principal methods of transmitting power and control signal to the end effector...
A capacitor is broadly defined as two conductors that can hold opposite charges. It can be used as either a sensor or an actuator. If the distance and relative position between two conductors change as a result of applied...
