Show that in a closed circuit the potential difference between the two ends of a cell is less than the emf of that cell.

2 difference between cell membrane and cell wall

Define standard emf of a cell.

A cell of emf 1.4V and internal resistance 2 Omega is connected in series with a resistance of 100 Omega and an ammeter. The resistance of the ammeter is 4/3 Omega .To measure the potential difference between the two ends of the resistance a voltmeter is connected .Draw the circuit

Write two difference between plant cell and animal cell .

A cell of emf 1.4V and internal resistance 2 Omega is connected in series with a resistance of 100 Omega and an ammeter. The resistance of the ammeter is 4/3 Omega .To measure the potential difference between the two ends of the resistance a voltmeter is connected IF the reading of the ammter is 0.02 A.what is the resistance of the voltmeter?

A cell of emf 1.4V and internal resistance 2 Omega is connected in series with a resistance of 100 Omega and an ammeter. The resistance of the ammeter is 4/3 Omega .To measure the potential difference between the two ends of the resistance a voltmeter is connected IF the reading of the voltmeter is 1.10V, what will be its error?

Resistance of a conductor is twice that of another conductor and the potential differences between the two ends of the two conductors are same. Find the ratio of strengths of currents flowing, through them.
