Considering normal resistive circuits:

If the resistance R of a circuit remains constant, when the voltage V is increased, the current I flowing through the circuit will be increased. This is a consequence of Ohm's Law which is V = I x R

Considering transmission lines:

In a transmission line the voltage is kept as high as possible so that the current remains as low as possible for a given amount of power P. This is a consequence of the Power Law which is P = V x I which can also be expressed as I = P / V

The current is kept as low as possible in a transmission line to ensure the minimum power loss due to current, because, for a fixed voltage, the actual power loss increases with an increase in current and decreases with a decrease in current. Again this is a consequence of the Power Law which is P = V x I

It depends upon what the circuit is for and what components it contains. For example, increasing the voltage on a high-voltage transmission line will have very little effect, but a small increase in a micro-circuit could cause damage.

Answer

In general, an increase in voltage will result in an increase in current.

A lamp will only operate at its rated power when subject to its rated voltage. If you increase the voltage, then the power output will also increase. For incandescent lamps, this is not a linear relationship, and small changes in voltage will cause larger changes in power output

Ohms law states that the current is directly proportional to the applied EMF (voltage) and inversely proportional to the resistance of the circuit.

If voltage is increased in a circuit what happens to current series and parallel respectively?

In this case current flows from a high voltage to a lower voltage in a circuit.


What happens to the current in the circuit if the resistance is increased?

If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.


What happens to the current in a circuit if the resistance is increase?

If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.


If the voltage applied to a circuit remains constant and the resistance in the circuit is increased the current will?

V = IR Where, V = voltage I = current R = resistance Thus if resistance is increased with constant voltage current will decrease


What happens to a circuit if the resistances is increased?

The voltage drop across each resistance will go up, and the current through the circuit will go down.


What happens to the voltage if the current increases?

Yes, if the resistance remains constant. Power is voltage times current, and current is voltage divided by resistance, so power is voltage squared divided by resistance. In essence, the power increases as the square of the voltage.

What is voltage error circuit and current error circuit?

A voltage error circuit is called an error amplifier and happens when there are discrepancies between the voltage output and the reference voltage. A current error circuit happens when there is a disruption of flow in an ammeter.


What happens when one bulb is added to a series circuit?

The resistance is increased, the voltage across each bulb is decreased and the current through the circuit is reduced.


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.
