Yes and no. Voltage is directly proportional to current from Ohm's Law (V=IR.) Thus, when voltage increases, so does current.
However, voltage can be inversely proportional to current in some situations. This can be seen in a transformer, where current and voltage are inversely proportional due to the law of conservation of energy, in which P(in) must equal P(out). Thus, a greater input voltage leads to a small output current.

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
When electric current is following in a curcuit if the voltage applied to the curcuit is increased the resistance will decrease true or false?
true
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.
Increasing voltage while maintaining the same resistance will cause current to decrease?
Decrease
How the current in a circuit changes if the voltage in the circuit is decreased and the resistance remains the same?
If the ratio of voltage to current is constant, then the circuit is obeying Ohm's Law. If the ratio changes for variations in voltage, then the circuit does not obey Ohm's Law.
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 type of device is used to increased or decrease the voltage of an electric current?
In an alternating current circuit the voltage can be stepped up ordown efficiently with a transformer.
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.
How in transmission line current decreases when voltage is increased?
Because power is power. If you maintain the same power, while increasing the voltage, you must decrease current. P=IE.
In a fixed voltage circuit where the resistance is increased voltage drops?
If the voltage is fixed, the using Ohms law: V=IxR If R increases, then the current will decrease proportionally.
When electric current is following in a curcuit if the voltage applied to the curcuit is increased the resistance will decrease true or false?
true
If the decrease voltage and the resistance stays the same is current increased or decreased?
This question follows Ohm's law which states, "Current is directly proportional to the applied EMF (voltage) and inversely proportional to the current in the circuit. <<>> decreased
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.
When current remains constant and resistance increases the voltage in the circuit will?
The physical equation governing voltage is V = IR, where V is voltage, I is current, and R is resistance. If V remains constant while R is increased, I or current must decrease. Increasing the resistance in a circuit is simply introducing a material that further resists or impedes the electron flow (current), thus current decreases.
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.
How do you decrease voltage in dc without decreasing amperage?
In order to decrease voltage without decreasing amperes you have to also decrease resistance. Ohm's Law: Voltage = current times resistance
Increasing voltage while maintaining the same resistance will cause current to decrease?
Decrease
