Answer #1

A)

Here in the above question following components and Resistor values were not given. The remaining values, emf = 6.5 v, internal resistance r = 0.620

The current in the circuit is the ratio of the emf of the battery with the total resistance and the total resistance will have the addition of the internal and the external resistance.

If the current passes through the cell a voltage is developed across the internal resistance of the cell this voltage is called terminal voltage.

The expression for the current is,

I = 6.50/(R+0.620)

Phsics Problem,Please show steps. A) You are given a battery, which has, of course, a particular emf and a particular internal resistance (Rint). You decide to determine its internal resistance and its emf by connecting an ammeter in series with a variable resistor across the battery. By varying the resistance you can draw more or less current from the battery. You also use a voltmeter to measure the voltage across the terminals of the battery. Case 1) When you draw...
