Questions & Step-by-Step Solutions
If the electric potential at point A is 5 V and at point B is 15 V, what is the potential difference between A and B?
Correct Answer: 10 V
Step 1: Identify the electric potential at point A, which is given as 5 V.
Step 2: Identify the electric potential at point B, which is given as 15 V.
Step 3: Use the formula for potential difference, which is V_AB = V_B - V_A.
Step 4: Substitute the values into the formula: V_AB = 15 V - 5 V.
Step 5: Calculate the result: 15 V - 5 V = 10 V.
Step 6: Conclude that the potential difference between point A and point B is 10 V.
Electric Potential Difference – The potential difference between two points is calculated by subtracting the electric potential at one point from the electric potential at another point.
