what is the formula of resistance

Answers

Answered by Kimsun

The resistance R in ohms (Ω) is equal to the voltage V in volts (V) divided by the current I in amps (A): Since the current is set by the values of the voltage and resistance, the Ohm's law formula can show that: ... If we increase the resistance, the current will reduce.

nagendrakumarsuriset: According to OHMS LAW

nagendrakumarsuriset: According to OHMS LAW V= IR, Here V = Voltage across the resistor.
I = Current across the resistor. Also R = pl/a. p(rho) = resistivity

Answered by beingankitaa

resistance of a conductor = potential difference of the conductor /current flowing through the conductor

nagendrakumarsuriset: For a conductor, resistance is positive temperature coefficient i.e., T increase , R increases.
For semiconductors its vice-versa. For cables the resistance is inversely proportional to length and vice versa for conductors.
