Ohm's Law states: V = IR, where V is voltage, I is current and R is resistance. If the voltage is constant, then current is inversely proportional to the resistance.

What is the relationship between the voltage and the current when the resistance is kept constant?
Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.
What happens to the current when the voltage is doubled and the resistance is constant?
I = E/R If resistance is constant, then current is directly proportional to voltage. Double the voltage ===> the current will also double.
What is the relationship between ohms resistance and amps for current?
The relationship is expressed by Ohm's Law: V=IR (voltage = current times resistance).
What law relates to voltage amperage and resistance?
Current is directly proportional to the applied voltage and inversely proportional to the resistance in the circuit. Short form, resistance goes up current goes down, resistance goes down current goes down.This answer is incorrect.First of all, resistance is not affected by a change in voltage or in current. Resistance is only affected by the length, cross-sectional area, and resistivity of the conductor (and, indirectly, by temperature which affects resistivity).Ohm's Law makes no mention of resistance. It simply states that the current flowing in a circuit is proportional to the applied voltage, providing external factors, such as temperature, remain constant.Since current is proportional to voltage, it must be equal to a constant times voltage. This constant is called conductance, which is the reciprocal of resistance, so the so-called 'Ohm's Law formula' is usually shown as I = V/R. But it's important to remember that the resistance, R, is a constant and does not change if V or I changes.
What is the relationship between voltage and current called?
It is called Ohm's Law; it's used a lot in analysis and design of circuits. The relationship is: V=IR (voltage = current x resistance).
What is the relationship between the voltage and the current when the resistance is kept constant?
Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.
What is a relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is the relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
How does voltage change in relation to current assuming that resistance remains constant?
Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.
What is the relationship among voltage circuit and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Does voltage versus current indicate a linear relationship?
Yes, provided the resistance is constant. If the resistance varies with current, then you have a non-linear circuit
What happens to the current when the voltage is doubled and the resistance is constant?
I = E/R If resistance is constant, then current is directly proportional to voltage. Double the voltage ===> the current will also double.
If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance
How does current vary with the resistance in the circuit if the voltage is constant?
Inversely. As resistance increases, current dereases; given that the applied voltage is constant.
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
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.
Will doubling the resistance in a circuit halve the current if voltage is held constant?
If resistance is halved while voltage remains constant, the current will double.
