What is the relationship among the potential drops across each resistor when the resistors are in series

V = V₁ + V₂ + V₃ + ... + Vₙ

Explanation:

When the resistors are connected end to end such that there is only one path for the current to follow, it is called a series arrangement of resistors. In the series arrangement of the resistors, the current across each resistor is the same as the current applied across the circuit.

The potential difference across each resistor is different in the series arrangement of the resistors. But the sum of potential differences across each of the resistors in the series arrangement of resistors is equal to the total potential difference applied by the battery or source. Therefore, if n number of resistors are connected in a series arrangement with a source of potential V, the:

V = V₁ + V₂ + V₃ + ... + Vₙ

Car A is not accelerating, but car B is accelerating

Explanation:

Car A is not accelerating because , it is moving with uniform speed in a particular direction . Therefore its velocity too is not changing .

But car B is accelerating because , though its speed is uniform but its velocity is changing due to change in direction . On a circular path , direction of speed changes every moment . Therefore it has an acceleration called centripetal acceleration . Hence car B has acceleration.
