Relation between Current, Temperature and Voltage is that when Temperature increases Current will decrease and Voltage will increase. And vice versa. You know ohms law, V=IR, where R is the resistance in ohms.

The relationship between current and voltage is direct - as voltage increases, current increases. The relationship between current and resistance is inverse. As resistance increases, current decreases (for a fixed voltage). The light bulb filament changes temperature and therefore changes resistance.

In other words, the current is directly proportional to the voltage and inversely proportional to the resistance. So, an increase in the voltage will increase the current as long as the resistance is held constant.

Temperature is directly proportional to the kinetic energy of the atoms that a body is made of. This relation is valid concerning the velocities relative to the center of mass of the body. In other words, concerted movements like translation and rotation do not affect temperature.

If a certain amount of current is flowing through a conductor, the current density in that conductor is equal to the product of the conductivity of the material of the conductor and the electric field created inside that conductor. We derived this law from Ohm's law.

Current is the rate of flow of charge. A current of 1 A means that 1 coulomb of charge flows past a point in a circuit every second. ( 1 A = 1 C s-1 ) Current is measured in a circuit using an ammeter which is placed in series with the component of interest in the circuit.

Voltage is the difference in charge between two points. Current is the rate at which charge is flowing. Resistance is a material's tendency to resist the flow of charge (current).

Understanding Current There are two types of current, direct current (DC) and alternating current (AC). DC is current that flows in one direction with a constant voltage polarity while AC is current that changes direction periodically along with its voltage polarity.

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).

Ohm's law defines the relationship between the voltage, current, and resistance in an electric circuit: i = v/r. The current is directly proportional to the voltage and inversely proportional to the resistance.

Current, Voltage and Resistance. ... 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.

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.

This equation, i = v/r, tells us that the current, i, flowing through a circuit is directly proportional to the voltage, v, and inversely proportional to the resistance, r. In other words, if we increase the voltage, then the current will increase. But, if we increase the resistance, then the current will decrease.

As temperature rises, the number of phonons increases and with it the likelihood that the electrons and phonons will collide. Thus when temperature goes up, resistance goes up. For some materials, resistivity is a linear function of temperature. The resistivity of a conductor increases with temperature.

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.
