Ohm's Law: V = I*R, so Voltage and Current are directly proportional and a change in voltage will result in a proportional change in current. (The current reduces by the same factor)

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
If you doubled the load resistor in a wheatstone bridge. the load current would not be half as much Why not?
Because by increasing the load resistance, the total circuit resistance is reduced. This means with less resistance, there is more current drawn from the source. Doubling the size of a load resistor increases the load current.
What happens in a circuit if the voltage is doubled and the resistance is held constant?
The answer depends entirely upon the scenario. Are you dealing with AC or DC? Does your circuit contain passive components or both passive and active components?For example, if you a simply dealing with a resistive DC circuit, you can derive your answer from Ohm's law, V = IR. Rearranging for current, I = V/R, so if you double the voltage, the current is subsequently doubled.
How will a current change if the resistance of a circuit remain constant while the voltage across the circuit decreases to half its original value?
Voltage = resistance X current abbreviated,V = C * RIf you halve the voltage of the current, then the other side of the equation must also be halved; therefore, you get:(1/2)V=(1/2)(C*R)which is the same as:(1/2)V=(1/2)(C)(R)which means that either the current or the resistance must be halved as well, and because the resistance stays the same, then the current is halved.
What is the Relationship between power factor and current?
When voltage and current waveforms are out of synch the power factor is reduced. In a pure resistance load the PF is 1. When inductance and capacitance is involved the PF is from 0 to 1.
What happens with electric current when applying the same voltage the resistance of the circuit is reduced?
As the resistance is reduced across the same voltage, the current increases.

What happens to the current flowing in a circuit if its resistance is doubled?
Using Ohms Law: V = I x R, where V (Voltage), I (Current), and R (Resistance). re-arranging: V/R = I Therefore if you double both the Voltage and the Resistance, the current remains unchanged.Current = Voltage / Resistance. If both resistance and voltage double the current remains the same.
What happens to voltage when resistance is increased?
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 would happen if you reduced the resistance in a circut?
current will increase
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.
As the total resistance is reduced in a simple electrical circuit the current flow will?
increase
If voltage stays the same and resistance increase what happens to electric current?
If voltage increases and the resistance stays the same the current must increase. According to Ohm's LawV~I (Directly Proportional) and V=RI where R is the constant of Proportionality, Resistance.
What happens in a circuit consisting of a voltage source and a resistor when the resistance is reduced by 35 percent?
I = V / R I = V / (0.65 R) I = 1.54 V / R Current increases by about 54%
What happens to the power if the resistance of a circuit doubles and voltage remains the same?
the power will be reduced to the haflf because P=V2/R so when the resistance doubles the power reduced to the half of itsoriginal value
What happen to current when paralle resistor added?
For the individual resistor, the current is constant, regardless of any other resister that's attached to it in parallel. The current that results from all the resistors combined decreases as the resistance of one or more of the resistors increases.
If you doubled the load resistor in a wheatstone bridge. the load current would not be half as much Why not?
Because by increasing the load resistance, the total circuit resistance is reduced. This means with less resistance, there is more current drawn from the source. Doubling the size of a load resistor increases the load current.
