What mathematical relationship do you see between voltage and current?
The mathematical relationship between voltage (V) and current (I) in an electrical circuit is described by Ohm's Law, which states that V = I * R, where R is the resistance in ohms. This means that voltage is directly proportional to current, with resistance acting as the proportionality factor. As resistance increases, for a constant voltage, the current decreases; conversely, for a constant resistance, an increase in voltage results in an increase in current. This relationship is fundamental in understanding how electrical circuits operate.
Is the change in resistance and conductance inversely linear?
Yes, the change in resistance and conductance is inversely linear. Resistance (R) and conductance (G) are related by the equation ( G = \frac{1}{R} ). As resistance increases, conductance decreases proportionally, and vice versa, demonstrating their inverse relationship. This relationship holds true as long as the material and temperature remain constant.
What is time constant of capacitor when resistance is zero?
Time constant in an RC filter is resistance times capacitance. With ideal components, if the resistance is zero, then the time constant is zero, not mattter what the capacitance is. In a practical circuit, there is always some resistance in the conductors and in the capacitor so, if the resistance is (close to) zero, the time constant will be (close to) zero.
Why isn't resistance constant?
If measuring resistance of materials or resistors by themselves(not soldered into a circuit board) resistance is constant. If measuring resistance of a circuit then it could fluctuate with the components functioning in the circuit.
What are the four technologies of training equipment?
constant resistance variable resistance and accomodating resistance

What is the relationship between current and resistance in a circuit when the voltage is kept constant?
In a circuit with constant voltage, the relationship between current and resistance is inversely proportional. This means that as resistance increases, the current flowing through the circuit decreases, and vice versa.
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 2.71828182845904?
It is the e mathematical constant, Euler's constant.
What is the relationship of current to resistance if voltage is constant?
According to Ohm's Law, the relationship between current (I), voltage (V), and resistance (R) is given by the equation I = V/R. Therefore, if voltage is held constant, an increase in resistance will result in a decrease in current, and vice versa.
If the resistance in a circuit is doubled while the voltage remains constant the current does what?
If resistance is doubled in a circuit with constant voltage, Ohm's Law (V=IR) states that current (I) would be halved since the voltage is constant. This is because the relationship between resistance and current is inversely proportional.
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
The mathematical relationship between current voltage and resistance is known as?
Ohm's LawAnswerIt's not known as anything; it's simply an equation. Ohm's Law describes constant proportionality between current and voltage for certain, but not all, materials (linear or ohmic) -it has nothing to do with this equation.
What is the relationship between resistance and length of a wire in detail?
I think that the relation is R = k/L where R is the resistance, L is the length of the wire, and k is the constant of proportionality.
What happens to the current when the voltage is doubled and the resistance is constant?
If the voltage is doubled and the resistance is constant, Ohm's Law states that the current will also double. This is because the relationship between voltage, current, and resistance is linear, and increasing the voltage will directly increase the current flow.
What are the dependent and independent variables in relationship between resistance and current at constant voltage?
dependent variable is current and independent variable is resisitance
What is constant resistance?
A resistance that doesn't change.
