Is it anyways possible by ohm's law that current/potential difference = constant . Please explain. If not then what is the result of current / potential difference

Solution

When the physical parameters such as Length, Area of cross section, Material, Temperature etc, remain constant then, the current flowing through the conductor is directly proportional to the potential difference applied across its terminals.

V = IR

I = V/R

R = V/I

The Constants are,

Resistance

Length

Area of cross section

Material

Temperature

Voltage and current will vary when the above constant are varried

Q. Explain the concepts of current, voltage, resistance, potential difference and ohm's law.

according to ohms law electric current is directly proportional to the potential difference across two ends then its mathematical form should be I~V why is it V~I

Why in a circuit with resistors in -
• parallel has potential difference constant in whole circuit but not current.
• series has current constant in whole circuit but not potential difference.
