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
First, this statement stands as long as voltage is constant. If you held the current constant then power would increase as resistance increases.V=IR. For a fixed voltage if you increase the resistance (R) then the current (I) will decrease - following the formula.Power = VI so as the resistance increases the value of VI (power) decreases as V is constant and I gets smaller.Therefore the power is decreasing as the resistance increases (when voltage is held constant).Hope this helps.
Resistance increases as temperature increases. If Voltage is held constant then according to Ohm's Law Voltage = Current x Resistance then current would decrease as resistance increases.
I think you mean when the 'potential difference' is high, is the current also high? The answer is that it depends on the impedance (a.c.) or resistance (d.c.) of the circuit. If this remains constant, then raising the potential difference will cause the current to increase too.
I assume you meant pressure to voltage. The resistance of a conductor is directly proportional to the temperature of the conductor. If the temperature of the conductor increases due to increased current, then the resistance tend to increase too.
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
Potential difference is directly proportional to resistance according to Ohm's Law. This means that as resistance increases, the potential difference across a component also increases, assuming the current remains constant.
At constant temp.& pressure,on the same circuit,with potential difference unchanged,current reduces if resistance increases.(Ohm's law).
If the potential difference across a resistor is doubled, the current flowing through the resistor will also double, assuming its resistance remains constant. This relationship is described by Ohm's Law, where current is directly proportional to voltage when resistance is held constant.
If the potential difference across a circuit is doubled, the current flowing through the circuit will also double, assuming the resistance remains constant. This is because Ohm's Law states that current is directly proportional to voltage when resistance is held constant.
Current increases if the voltage remains constant.
Inversely. As resistance increases, current dereases; given that the applied voltage is constant.

increases. Time constant, denoted by τ, is equal to the product of resistance (R) and capacitance (C), τ = RC. If the resistance increases, it will take longer for the capacitor to charge or discharge, resulting in a longer time constant.

As the object falls, potential energy decreases while kinetic energy increases. The total mechanical energy (sum of potential and kinetic energy) remains constant in the absence of air resistance.
A non-ohmic resistor doesn't have a constant resistance. A ohmic resistor has a constant resistance.
