Question

Which of the following relation between electric field (E) and electric
potential (V) is correct?​

Answer 1

Answer:

potential gradient gives this relationship.

dE=dV/dX

Answer 2

Answer:

ohms law

• Explanation

• v is direction proportional to A
• HENCE V=IR(r=constant proportionality)
• r=resistance
• ohms law only follows ohmic conductors
• thses law follows at consatant temperature
• grap bw v and I GIVES RESISTANCE
• ALWAYS GIVES STRAIGHT LINE
• IT IS APPLICABE FOR ANY VALUES
