At pinch off voltage, the channel is blocked at its maximum. (depletion region blocks almost entire channel, so no charge exchange).
Therefore, no drain is flown through the channel.
It is halved. coz voltage=current * resistance
Voltage remains constant; current increases.
If the voltage is doubled and the resistance is constant, Ohm's Law states that the current will also double. This is because the relationship between voltage, current, and resistance is linear, and increasing the voltage will directly increase the current flow.
If the resistance of the load is kept more-or-less constant, then the current also becomes larger. On the other hand, if the power of the load is kept more-or-less constant, then the current becomes smaller.
If the load resistance is constant, then increasing the voltage will increase the current by the same proportion -i.e. doubling the voltage will double the current.
the current remains constant as more magnetic lines are free
Since resistance is the ratio of voltage to current, we can say that halving the resistance will result in twice the current.
Power dissipation in a conductor is given by the formula ( P = I^2 R ), where ( P ) is power, ( I ) is the electric current, and ( R ) is the resistance. If the electric current is doubled, the new current becomes ( 2I ). Substituting this into the power formula results in ( P' = (2I)^2 R = 4I^2 R ), which shows that the power dissipation increases by a factor of four. Therefore, doubling the current through a constant resistance results in a fourfold increase in power dissipation.
It depends on what the new owner plans to do with your unit. You can ask the current owner if he knows.
The circuit becomes a pure resistance circuit where current and voltage are in phase with each others.
in a parallel circuit, current get divided among the parallel branches in a manner so that the product of current and the resistance of each branch becomes same. The sum of the current in each branch is equal to the total current of the circuit.
Ohm's Law: V = I*R, so Voltage and Current are directly proportional and a change in voltage will result in a proportional change in current. (The current reduces by the same factor)
