according to the ohm's low if we increase the resistance the current decreases. As ohm's low states voltage is directly proportional to the current and resistance. So current can defined as the ratio of voltage to the resistance, as large the resistance, as low the current.
the effect of cutting the resistance have on the current is that the current will increase its voltage because only the resistance will hold the current from passing through directly in a certain objects.

V = iR is Ohm's law, where V is voltage, i is current, and R is resistance.
If i goes up, but R stays the same, then V will go up, as V and i are directly proportional.
How is this in the "Environmental Issues" category?
AnswerOhm's Law states that 'the current flowing through a conductor, at constant temperature, is directly proportional to the potential difference across the ends of that conductor'.
For Ohm's Law to apply, the ratio of voltage to current must be constant over a wide range of changes in potential difference. In other words, the resistance must remain constant over a wide range of changes in potential difference. As this is the case with your question, a doubling in current would double the potential difference appearing across the resistor, and so on.
Note that the equation R = V/I is derived from the definition of the ohm, has nothing to do with Ohm's Law, and applies whether Ohm's Law applies or not.
If voltage increases when current remains constant then resistance must also increase. Ohm's Law: Voltage = Current times Resistance.
Ohms Law says Voltage = Current x Resistance. Hence if voltage rises, so will current.
If Rotor resistance is increased torque is increased
it increases
When the value of the load resistance in a transformer is changed, it will affect the current flowing through the circuit. Increasing the load resistance will decrease the current, while decreasing the load resistance will increase the current. This change in current will in turn affect the voltage across the load and the efficiency of the transformer.
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
The current decreases due to I=V/R. The ammeter reading will decrease as R is increased.
If voltage increases when current remains constant then resistance must also increase. Ohm's Law: Voltage = Current times Resistance.
Ohms Law says Voltage = Current x Resistance. Hence if voltage rises, so will current.
If Rotor resistance is increased torque is increased
it increases
According to ohms law, V = IR, where V=voltage I= current R = resistance the above formula can also be written as I = V/R, here, resistance is inversely proportional to current. In other words, as resistance increases, current decreases.
According to ohms law (V=IR)if voltage is increased the current also increases keeping the resistance same .In other words, to keep values on the both sides of equal sign current must increase with the voltage when the resistance is constant. For example: if R=1 and V=2 then I=2 and if voltage is increased to 4 then current also increases with voltage to 4.CONCLUSION:V IS DIRECTLY PROPORTIONAL TO I KEEPING THE R CONSTANT
Nothing, but the current will increase.
current will increase
If the resistance increases, while the voltage stays the same, current will decrease. Current = voltage divided by resistance
Your question seems to have an idea in it backwards.
