Ohms law is V=I X R. If resistance (R) is reduced and current (I) is constant, then voltage (V) must decrease. You can see from the equation that they are proportional to one another. If, however, R is reduced and V is held constant, then I must increase (I and R are inversely proportional). The only way V can increase is if either or both I and R increase.

What happens to the current in a circuit if the voltage is kept constant but the wire diameter is increased?
If the voltage in a circuit is kept constant and the wire diameter is increased, the resistance of the wire decreases. According to Ohm's Law (I = V/R), where I is current, V is voltage, and R is resistance, a decrease in resistance results in an increase in current. Therefore, with a larger wire diameter, more current will flow through the circuit at the same voltage.
If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance
What will happen too amperage if voltage is increased and resistance remains the same?
Ohms Law says Voltage = Current x Resistance. Hence if voltage rises, so will current.
What happen to the current when the voltage increased if the resistance are constant?
If voltage increases when current remains constant then resistance must also increase. Ohm's Law: Voltage = Current times Resistance.
What happens to the current in a device if the resistance of the device increases and the voltage difference stays the same?
If resistance increases and voltage stays the same, then current decreases. Ohm's Law: Current equals Voltage divided by Resistance.
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.
What happens to the electric current in a wire as voltage is increased?
As voltage is increased, the electric current in a wire also increases because the relationship between voltage, current, and resistance is described by Ohm's Law (V = IR). If resistance remains constant, a higher voltage will result in a higher current flowing through the wire.
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
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.
What happens to the current in a circuit if the voltage is kept constant but the wire diameter is increased?
If the voltage in a circuit is kept constant and the wire diameter is increased, the resistance of the wire decreases. According to Ohm's Law (I = V/R), where I is current, V is voltage, and R is resistance, a decrease in resistance results in an increase in current. Therefore, with a larger wire diameter, more current will flow through the circuit at the same voltage.
If the value of resistance increased then?
If the resistance is increased the current, which is inversely proportional, decreases and, the voltage drop increases.
What will increase voltage if current is increased?
a constant resistance
What happen to the current in a 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 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 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.
What happens to the brightness of a bulb if the volts are increased?
The electrical potential energy increases as the voltage is increased. It further excites the filament in the bulb more than a lessor voltage would. Using good old ohm's law (Voltage = Current x Resistance), a larger voltage applied to a bulb at the same resistance increases the current proportionally and larger currents has the effect to cause higher temps in conductors
