What are the changes to the resistance and the voltage will always increase the current in a circuit
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.
AnswerIn 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
The brightness of a bulb in the circuit,Current, power
The heat produced by the current will increase. More voltage means more electricity, which leads to more heat.
If you increase the current in an ordinary incandescent light bulb, the light bulb will get brighter.
Ohms law states that the current is directly proportional to the applied EMF (voltage) and inversely proportional to the resistance of the circuit.
it gets brighter
Power and Current
V = IR Where, V = voltage I = current R = resistance Thus if resistance is increased with constant voltage current will decrease
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.
When an alternating voltage is applied to a purely resistive circuit, the resulting current is in phase with the voltage.
If you are referring to a simple circuit, you could add resistance throughout it. Increased resistance means decreased current flow yet the same voltage.
Voltage is equal to the Current multiplied by the Resistance.Without changing the resistance, increasing the applied voltage in a circuit will increase current flow. There is a simple, direct relationship between voltage and current. Double the voltage, twice the current will flow. Triple the voltage, and the current will triple. As voltage (E) equals current (I) times resistance (R), when resistance is fixed, what happens to voltage will happen to current.
In this case current flows from a high voltage to a lower voltage in a circuit.
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
V = IR Where, V = voltage I = current R = resistance Thus if resistance is increased with constant voltage current will decrease
The voltage drop across each resistance will go up, and the current through the circuit will go down.
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.
It increases
Correct Answer= "the current will increase"
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.
The resistance is increased, the voltage across each bulb is decreased and the current through the circuit is reduced.
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.
