Ohm's law states the same thing. E = I x R, substitute numbers for E and I and see for yourself. E = 120, I = 10, R = , now E = 60, I = 10, R = what number times 10 = 60

If voltage remains constant and resistance decreases current flow?
the current will increase because of a lower level of resistance , hence more current will flow- easily
When resistance decreases what happens to current?
Based on the simplest Electrical Equation V = I * R,(reads: voltage equals current multiplied by resistance)then, rearranged I = V / R .As resistance decreases, current flow proportionately increases
Can voltage decrease when current is increased?
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.
In a series circuit each device that is added to the circuit decreases the what?
Depends on the device. If it is a resistor and you have a fixed voltage then the circuit will obey Ohms law. Voltage = Current x Resistance. So if R increases by adding more resistors in series and the voltage is constant, the current will decrease.
Increasing voltage while maintaining the same resistance will cause current to decrease?
Decrease
Technician A says that the current draw should decrease as the voltage decreasestechnician B says that the current should increase as the voltage decreases Which technician is right?
Both technicians are right, and both technicians are wrong, because not enough information is present in the question, nor in their statements. Given constant impedance, current should decrease as voltage decreases, while given constant power, current should increase as voltage decreases.
As the DC voltage applied to a circuit decreases what will the current do?
In a passive circuit, the current will decrease. In an active industrial circuit, it will usually decrease. In a theoretic manner - it is an unknown.
If voltage remains constant and resistance decreases current flow?
the current will increase because of a lower level of resistance , hence more current will flow- easily
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.
How does load current vary with the load resistance?
Their relationship is only dependent on the voltage lost across that resistor; voltage equals resistance times current, so increasing the current for a given voltage will require a decrease in the resistance, and vice versa.
If power is constant increasing the voltage will increase or decrease current?
Decrease, because W = I (current) x V (voltage), if one increases, the other decreases in proportion to the increase of the other. Ohm's Law states current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.

How do you increase or decrease voltage?
This question makes no sense as written. However, maybe it will help to know that for a given load if you increase voltage the current increases proportionally and if you decrease the voltage the current decreases proportionally. Ohm's Law says Voltage = Current x 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.
Does electrical current generally increase as resistance decreases?
Ohm's Law Voltage = Current x Resistance. So for a fixed voltage as R decreases then current increases proportionally.
VOLTAGE is decreased then what about CURRENT?
Ohm's law: I=E/R I=Current, E=Voltage, R=Resistance. If E decreases and R remains the same, I decreases.
