Question

what is a formula for finding internal resistance of cell??

please follow me​

Answer 1

Answer:

The relationship between internal resistance (r) and emf (e) of cell s given by. ... e = I (r + R) Where, e = EMF i.e. electromotive force (Volts), I = current (A), R = Load resistance, and r is the internal resistance of cell measured in ohms

Answer 2

Answer:

The relationship between internal resistance (r) and emf (e) of cell s given by.

e = I (r + R)

Where, e = EMF i.e. electromotive force (Volts), I = current (A), R = Load resistance, and r is the internal resistance of cell measured in ohms.
