What is a overcurrent device?
a device protecting conductors or other equipment in a circuit from an overload/overcurrent situation
What are electrical fuses?
Safety devices used in electrical circuits.AnswerA fuse is an overcurrent protection device, and will operate in the event of a sustained overload current or a short-circuit current.
Difference between overcurrent relay and fuse?
Current is flow of electricity charge. Voltage is a measure of potential energy or charge. Fuse. Is a device that opens when the current rating is exceeded this stopping the flow of current.
What is an electrostatic discharge and why does it occur?
A VERY BIG PROBLEM practically all electronics are restricted to voltages no greater 40 50 volts electrostatic can be as much as 5kv to 50 kv but the source impedance is very hi so while the voltage is there current capabilities are not a low impedance device can possibly survive these discharges but a hi impedance device like MOS cannot survive since the negligent current will raise the potential very hi blowing the device.
A device that protects a circuit from current overload is called?
Fuses or circuit breakers are termed 'overcurrent protection devices', which protect circuits from either an overload current or a short-circuit current.
What does OPD mean in electric terms?
'Overcurrent protection devices' are used to protect conductors from excessive current flow... a fuse
What is a overcurrent device?
a device protecting conductors or other equipment in a circuit from an overload/overcurrent situation
Which device has its characteristics very close to that of an ideal current source?
A: A current source can be defined as a zero impedance source. A battery is essentially a zero impedance since it can provide lots of current with zero volts out
What is an overcurrent device?
breakers and fuses
What device has the smallest current in parallel circuit?
The one with the highest resistance (or impedance, if the voltage is not DC).
Why bjt is called current controlled current device?
Because the operation of the transistor is determined by the current at the base. the principle equations of BJT operation are: Ic = h*Ib ,and Ie=Ib+Ic thus device operation is controlled by the input current.
What are the functions of an electrical circuit beaker?
A: Its function is to trip if the current across it coil is its tripping pointAnswerA circuit breaker is an overcurrent protection device which can break a fault current.
What are electrical fuses?
Safety devices used in electrical circuits.AnswerA fuse is an overcurrent protection device, and will operate in the event of a sustained overload current or a short-circuit current.
How are branch circuits rated?
By the rating of the overcurrent device.
Can an impedance matching device reduce electrical costs?
An impedance matching device is used to test the resistance, inductive reactant and capacitive reactant in a circuit. If one component did not match the impedance of the conductor, some of the current will be lost by the conductors itself. In conclusion if electricity is lost, the component needs to meet its regular voltage. It consumes more voltage than expected because of the loss. Impedance matching device can actually reduce electrical cost.
What circuit protection device can be reset after it opens?
A circuit breaker is an overcurrent device that can be reset after it has opened.
Difference between overcurrent relay and fuse?
Current is flow of electricity charge. Voltage is a measure of potential energy or charge. Fuse. Is a device that opens when the current rating is exceeded this stopping the flow of current.
