what is the mathematical relationship between potential difference current and resistance?

Current is directly proportional to electric potential difference and inversely proportional to resistance.

The same current flows through each part of a series circuit. The total resistance of a series circuit is equal to the sum of individual resistances. Voltage applied to a series circuit is equal to the sum of the individual voltage drops.

The relationship between current, voltage and resistance is expressed by Ohm's Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant.

The equivalent resistance of resistors in series is: Req = R1 + R2 + R3 + ... The single equivalent resistor has the same current through it as each resistor in the series circuit, and the potential difference across it equals the total potential difference across the whole chain of resistors.

The resistance is inversely proportional to the square of the radius because that gives the electrons more metal to flow through with less resistance. R is directly proportionally to length(l) and inversely proportional Area(A). If radius increase then resistance decrease and vice versa.

Ohm's Law and Resistance. Ohm's law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance, and directly proportional to the resistance of the circuit. The formula for Ohm's law is V=IR.

['The resistance, R of the conductor. A higher resistance produces more heat.', 'The time, t for which current flows. The longer the time the larger the amount of heat produced.', 'The amount of current, I.']

Resistance is a constant pushback against electrical force, much like friction. Inductance is resistance to a change in electrical force, much like inertia. If current flows through a circuit with high inductance, the current will continue flow at a similar rate, resisting any changes to the flow.

The potential difference in a circuit is what causes current to flow through the circuit. The larger the potential difference, the faster the current will flow and the higher the current. The potential difference is the measure of the difference in voltage between two distinct points in a closed circuit.

All resistance are connected in series combination so Total resistance is equal to summation of all resistance. Total resistance = 6 ohm. Now potential difference across 3 ohm resistor, V = IR. so Potential difference across 3 ohm resistor V = 3*1/3 = 1 Volt.

Resistance is simply defined as the opposition to the flow of electric current in the circuit. Impedance is opposition to the flow of AC current because of any three components that is resistive, inductive or capacitive. It is a combination of both resistance and reactance in a circuit.

Resistance is inversely proportional to the square of the diameter of a wire. If diameter is doubled then resistance is reduced by 4 times.

We can say that, for a metal wire at constant temperature, the resistance is directly proportional to the length of the wire. If you double the length of the wire you double its resistance.

For a fixed resistor, the voltage is directly proportional to the current. Doubling the amount of energy into the resistor results in a current twice as fast through the resistor. This relationship is called Ohm's Law and is true because the resistance of the resistor is fixed (because the temperature does not change).

The standard formula for calculating voltage is defined by Ohm's Law. It states that E(electromotive force or volts) = I(current passing through) x R(impedance in ohms in purely resistive circuit or Z, impedance in ohms of a circuit containing resistors and non linear impedances(inductors and capacitors).

The relationship of flow (Q), resistance (R), and pressure difference (∆P) is expressed by Ohm's law (Q=∆P/R). The magnitude of blood flow is directly proportional to the pressure difference. The direction of blood flow is determined by the direction of the pressure gradient from high to low pressure.

Per my graph the relationship between the force and the current is adirect/proportional relationship. When one increases so does the other andvice versa.
