Is potential difference between different points of the circuit same or different

Expert Answer:

Whether the potential difference is same or different depends upon the connection of appliances or resistors in circuit. 
 
1. If the resistors/ appliances are connected in series then the potential difference across the ends of appliances or resistances will be different. 
 
For example: - 
Observe the following series combination: - 
 
 the 4 ohm and 5 ohm resistors are connected in series thus if you measure potential difference across 4 ohm and then across 5ohm you will observe that potential difference across these two resistors will be different. 
 
 
2. If the resistors/ appliances are connected in parallel then the potential difference across the ends of all the resistances/appliances connected in parallel will be same. 
 
For example: - 
 
From the above figure, you will see that 2 ohm and 3 ohm resistor are connected in parallel to each other thus the potential difference across these two resistors are same.
