Voltage is pressure and current is flow what opposes flow?
Reverse current.
What is the electrical property that opposes change in current?
inductance
What does a inductor do when connected across ac supply?
opposes changes in current
What is current capacity?
It refers to a device any device whereby the device has limit to carry current. Therefore the term current capacity
Is BJT is a current control device or voltage control device?
transistor is a current controlled device. as the current flows through the base of the transistor , it works like a close switch.
Name device which permits direct current and opposes the flow of alternating current?
A diode does that.
An inductor opposes a change in?
Current.
Voltage is pressure and current is flow what opposes flow?
Reverse current.
What is the electrical property that opposes change in current?
inductance
What opposes the flow of electric current?
Resistance in OMS: In alternating current is is measured in impedance.
What does a inductor do when connected across ac supply?
opposes changes in current
Why induced current in a coil opposes the EMF producing it?
lenzs law

What opposes the flow of an electric currents?
Resistance in OMS: In alternating current is is measured in impedance.
Why does the induced current opposes the original cause in lenz's law?
The induced current creates a magnetic field that opposes the original cause of it because it is trying to resist the change in magnetic field in the area and the only way to do that is to create an equal and opposite magnetic field which leads to the induced current.
Is BJT is a current control device or voltage control device?
transistor is a current controlled device. as the current flows through the base of the transistor , it works like a close switch.
What is the statment of lenz law?
The direction of an induced emf or current is such that the magnetic field created by the induced current opposes the change in magnetic flux that created the current.
