Sample Data
| Front | Internal resistance: if the resistance of a variable resistor is increases...why does this happen? (2 explanations) |
| Back | The terminal voltage increases.Explanation 1:Share of the emf goes more towards the variable resistor and less towards the internal resistor.Explanation 2:The current is now lower ⇒ fewer lost volts |
