There is no circuit shown in your question. It is not possible for us to see your homework paper and answer this question.
According to ohms law, V = IR, where V=voltage I= current R = resistance the above formula can also be written as I = V/R, here, resistance is inversely proportional to current. In other words, as resistance increases, current decreases.
A thyristor will conduct only if enough gate current is present on the gate and enough holding current flow trough it. Once on it will remain on until the holding current is reached then it will not conduct. Since AC is changing polarity it is possible to apply gate current at any time to make it conduct it will turn off when the AC cannot supply the holding current making it an ideal phase controller
The current level that results in your brain's commands being swamped out; I've heard this called the "let go" threshold as well. If this amount of current is flowing through your hand, you won't be able to let go of whatever it is you were holding.
It is a current
we know that ratio of holding current to latching current in scr is 0.4.
Using Ohms Law: V = I x R, where V (Voltage), I (Current), and R (Resistance). re-arranging: V/R = I Therefore if you double both the Voltage and the Resistance, the current remains unchanged.Current = Voltage / Resistance. If both resistance and voltage double the current remains the same.
Having low resistance means that there is an easier flow of electric current through a circuit. This can lead to higher current levels which could potentially damage the components in the circuit or cause overheating. It can also result in a decrease in voltage across the circuit.
1. Increase the voltage while holding the resistance constant.and2. Decreasing the resistance while holding the voltage constant.For a fixed load, increase the supply voltage. For a fixed supply voltage, increase the load.So that there is no confusion, 'increasing a load' means reducing the resistance (in the case of a d.c. circuit) or reducing the impedance (in the case of an a.c. circuit).
A conducting thyristor can be turned off by reducing the current flowing through it below the holding current value. This can be achieved by interrupting the current flow using a circuit breaker, reverse biasing the thyristor, or triggering the thyristor with a gate signal that transitions it into a non-conducting state.
The function of a battery snap is to stop the current from the battery from flowing whenever you want to, and so that its safer.

The current will increase and will flow more. If voltage increases, current must increase.

Fly wheeling or ringing is a process where by circulating current will cause a ringing effect where that is useful is on SCR circuit to reverse power for a shot time enough to reduce holding current therefore shutting the device off
segnificence of holding current
Current in a purely inductive circuit lags the voltage by 90 degrees. The apparent power in such a circuit will be zero, because the power factor is zero, however, energy will still be transferred, and VARs (Volt-Amps-Reactive) will be non-zero.
