What will happen if the resistance of the conductor increased?
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.
What is grip current?
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.
How do you use a thyristor on a ac circuit?
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
What is holding current of SCR?
It is a current
How do you calculate holding current of scr when latching current is given?
we know that ratio of holding current to latching current in scr is 0.4.
What happens to the current flowing in a circuit if its resistance is doubled?
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.
Describe two ways to increase the current in a 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).
What is a battery snap used for?
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.
What happens when you have low resistance?
When you have low resistance, it means that it is easier for you to go. If there is not as much as resistance with something holding you back,?æthen you can go faster, and not be held back.
What will happen if the resistance of the conductor increased?
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.
What is the effect on current through a circuit of steady resistance when the voltage is doubled?
The current will increase and will flow more. If voltage increases, current must increase.

Explain what happens to current in a purely inductive circuit?
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.
Explain flywheel effect of a tank circuit?
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
What is the cost of holding current assets?
segnificence of holding current
Application of diac?
The diac acts like an open-circuit until its switching or breakover voltage is exceeded. At that point the diac conducts until its current reduces toward zero (below the level of the holding current of the device). The diac, because of its peculiar construction, does not switch sharply into a low voltage condition at a low current level like the SCR or triac. Instead, once it goes into conduction, the diac maintains an almost continuous negative resistance characteristic, that is, voltage decreases with the increase in current. This means that, unlike the SCR and the triac, the diac cannot be expected to maintain a low (on) voltage drop until its current falls below a holding current level.
