Which terminal of the battery has higher potential?
Answers
Answer:
please mark as brainliest
Explanation:
The positive terminal of a battery is higher in electric potential than the negative terminal by an amount which is equal to the battery voltage.
+ve terminal...
but..
It's really just a convention, a definition. Scientists define electrical potential in terms of the effect on a positive charge. They could have done it the other way around.
The allocation of the terms "high potential" and "low potential" to the terminals of a battery uses the convention of electric fields. It's based on the direction in which a small positive "test charge" would move in the presence of an electric field.
Work is needed to move a positive test charge towards a source of positive charge. That increases the potential energy of the test charge. Moving a positive test charge towards a negative charge will decrease the potential of the test charge. You should now understand why the positive terminal of a battery is called the high potential end.
