(a)
Interpretation:
The potential difference across each of the resistors is to be stated.
Concept introduction:
The potential difference which is also known by various names like voltage or electric potential difference is defined as the difference in electric potential between two specific points in an electric circuit.
(b)
Interpretation:
The magnitude of each current is to be stated.
Concept introduction:
The current can be defined as the amount of electric charge flowing through a particular section per unit time. Current through an element is directly proportional to the potential difference across that element in the circuit.
(c)
Interpretation:
The power dissipated by the resistor
Concept introduction:
The phenomenon which results in the generation of heat as a part of the product due to friction or resistance is termed as power dissipation.
(d)
Interpretation:
The potential difference between point
Concept introduction:
Potential difference which is also known by various names like voltage or electric potential difference is basically defined as the difference in electric potential between two points.
