A shunt is a device that is designed to provide a low-resistance path for an electrical current in a circuit. It is typically used to divert current away from a system or component in order to prevent overcurrent .
Shunt resistor. The common and simple approach to current sensing is the use of a shunt resistor. That the voltage drop across the shunt is proportional to its current flow, i.e. ohm's law, makes the low resistance current shunt a very popular choice for current measurement system with its low cost and high reliability.
Shunting inhibition is theorized to be a type of gain control mechanism, regulating the responses of neurons. [5] [6] Simple inhibition such as hyperpolarization has a subtractive effect on the depolarization caused by concurrent excitation, whereas shunting inhibition can in some cases account for a divisive effect.
A coil of wire used to create a magnetic field; often a device with a ferromagnetic plunger that moves when the coil is energized. solid state Electronics that relies on current flow through crystalline lattices. solid state physics That branch of physics that studies arrangements of atoms in fixed arrays. sound recording
A shunt-trip unit appears similar to a normal breaker and the moving actuators are ganged to a normal breaker mechanism to operate together in a similar way, but the shunt trip is a solenoid intended to be operated by an external constant-voltage signal, rather than a current, commonly the local mains voltage or DC. These are often used to cut ...
a shunt, the simplest design, uses the main winding for the excitation power; an excitation boost system (EBS) is a shunt design with a separate small generator added to temporarily provide an energy boost when the main coil voltage drops (for example, due to a fault). The boost generator is not rated for permanent operation;
A shunt generator is a type of electric generator in which field winding and armature winding are connected in parallel, and in which the armature supplies both the load current and the field current for the excitation (generator is therefore self excited).
Transcranial direct current stimulation (tDCS) is a form of neuromodulation that uses constant, low direct current delivered via electrodes on the head. This type of neurotherapy was originally developed to help patients with brain injuries or neuropsychiatric conditions such as major depressive disorder.
