That depends on the circuit - but note that in almost all real circuits the current is the dependent variable - you control the voltage and the current sets itself.

What is difference between skin effect and franty effect?
skin effect that happen because the current pass at the edge of the cable in the ac current because of the frequency but in the dc the current pass throw the whole conductor the franty effect the stray capacitor increase the voltage on the line due to light load and the
Why is it written as V equals IR why not as I equals VR?
the main point is that.... by increasing of voltage the current will be increase...not by increasing of current voltage is increase....in that way we write that V is directly proportional to I...
An increase in temperature will the attenuation of a cable?
Basically we should also keep in mind knowledge about voltage and current. If we keep voltage constant then by increase in temperature also increase the attenuation, if we keep current constant then attenuation drops by increasing temperature.
What happen to voltage sensitivity if current sensitivity is increase of agalvanometer?
it also increases
How do you increase the amount of current created by a generator?
You can use a transformer to increase the current. Note that this will also decrease the voltage. The total energy will not increase; it will decrease slightly, due to losses in the transformer.
What would be the effect of increasing the voltage of the battery?
Ohm's Law states that Voltage = Resistance (Ohms) * Current (Ampere). So when you increase voltage, you increase current.
If Three 12 volt batteries are connected in parallel what is the effect on the circuit?
There will be no effect on the voltage. That is the effective voltage will be only 12 volt. But there will be increase of current.
If we increase the current then what about the power factor?
The power factor depends on the phase angle between the voltage and current on a conductor. The amplitude of the current has no effect on it.
What is the effect of surge arrester on increase the voltage in medium voltage circuits?
What is the effect of surge arrested on increase the voltage in medium voltage circuits?
Should you increase voltage or resistance to increase flow in a circuit?
To increase (current) flow in a circuit you increase voltage (or decrease resistance). Ohm's Law: Current = Voltage divided by resistance
Will current increase if the voltage in a circuit is increased?
Ohm's Law states Voltage = Current x Resistance. Hence if voltage is increased and resistance is constant, current will increase proportionally to the rise in voltage.
Why current leads in capaciter?
Capacitors resist a change in voltage. It takes current to effect a voltage change, resulting in the current "leading" the voltage. Similarly, inductors resist a change in current. It takes voltage to effect a current change, resulting in the current "lagging" the voltage.
What is effect of voltage and current by changing the length of wire?
By changing the length of wire, say reducing it, the resistance will drop and that will increase current flow but the voltage is less likely to change V=IR.
What increases when current increases?
If current increases, then voltage also has to increase, assuming that resistance stay relatively the same. Power will also increase. Since power is the product of voltage and current, then the power increase would be the square of the voltage or current change.
Why does increasing the voltage of a wire have the same effect on the current that decreasing the resistance has?
Ohm's Law is Voltage = Current x Resistance or written v - I x R. So if you raise the voltage and keep R the same current must increase to satisfy the equation. I = V/R. Similarly if you reduce R and keep V the same current will also increase proportionally.
Effect on voltage as current increases through constant resistance?
If the current is held constant, the voltage will decrease.
When tempratere increase resistance increase and when resistance increase current decrease why?
That's what "resistance" is all about: reducing the current for a given voltage. In fact, you can DEFINE resistance as voltage divided by current.
