The On/OFF action in UJT is controlled by emitter current
Because it is controlled by the gate current
A path that is made for an electric current is called a circuit. The two main components in a circuit are the load and a source which are combined with conductors and as a whole form a circuit.
A continuous flow of negative charges is called an electric current.
In the simplest case, that would be resistance - but there is also another type of opposition (only relevant for AC) called reactance. The combined effect of resistance and reactance is called impedance.
That is called Ohm's Law.
"Opposition to current" can refer to resistance, reactance, or impedance.

The opposition to the flow of current in a circuit is called resistance. Resistance is measured in ohms and is represented by the symbol Ω.
The force moving electrons in electricity is called resistance. The electrons move toward a path of least resistance. The current is the actual movement of the electrons in a specific direction.
A continuous flow of negative charges is called an electric current.
In the switching transistor the output current is controlled by the (current) and this is also called current controlled current device (CCCD). But in ordinary switch we controlled output current physically...
It is nothing but giving current in opposite direction (positive to negative andnegative to positive)
Previous answer "TRANSISTORS are current controlled voltage soruce" Nup, current-controlled current controller. Named as a contraction of TRANSference resISTOR.

The difference between a current control device and voltage controlled device is that for current controlled device, the current is constant and the voltage is variable while for a voltage controlled device, the voltage is constant and the current is variable.
That is called Ohm's Law.
