Ohm's law relates the current, voltage, and resistance in a circuit. Use Ohm's law to determine what will happen to the remaining variable if one is held constant and another is changed. Assume that, originally, the resistance is R 0 , the current is I 0 , and the voltage is V 0 .

Answer:

Step-by-step explanation:

According to the Ohm's law, when the temperature of a conductor remains constant, the current flowing through the conductor is directly proportional to the potential difference applied across the conductor.

V = I R

where, I is the current and R be the resistance of the conductor.

When the resistance remains constant, if we increase the potential difference across the conductor, the current also increases.

Answer:

Ohm's Law states that current through any conductor is directly proportional to the potential difference across the ends of the conductor.

Step-by-step explanation:

Ohm's Law states that current through any conductor is directly proportional to the potential difference across the ends of the conductor.

Mathematically:


I\propto V


I_0=(V_0)/(R_0)

where

R = resistance of the conductor

i.e.

  • When resistance is held constant the current is directly proportional to the voltage.

Other form of the equation is:


V_0=R_0.I_0

  • For a constant current the voltage is directly proportional to the resistance of the conductor.


V_0\propto R_0

  • For constant voltage the current is inversely proportional to the resistance of the conductor.


I_0\propto (1)/(R_0)
