Define : Terminal potential differences.

Answer the following question: Define electric potential difference.

Answer the following question: Define potential difference.

Define electric potential difference between two points in an electric field. Is it a scalar or vector?

In potentiometer experiment, if l_1 is the balancing length for emf of cell of internal resistance r and l_2 is the balancing length for its terminal potential difference when shunted with resistance R then

When a resister of 10Omega is connected across a cell, its terminal potential difference is balanced by 150cm of potentiometer wire and when 20Omega resistance is connected across the cell, terminal potential difference is balanced by 175cm of the same potentiometer wire. Find the balancing length when the cell is in open circuit and also find the internal resistance of the cell.

Write formula: Potential difference

Define electric potential.

Fill in the blanks: The potential difference between the terminals of a cell is caused by…………occuring inside the cell.

Define electric potential

A potentiometer is an ideal instrument for measuring potential difference or e.m.f. because
