Question

to study the potential difference across a combination of resistors in series​

Answer 1

Answer:

The potential difference across R2 = V2 = I R2. The potential difference across R3 =V3 = I R3. Thus, in case of series connection, the equivalent resistance, Req = V/I = (R1+ R2+ R3). ... Thus, in a series connection, the total resistance of a circuit is determined by adding the resistance of each individual resistors.

Answer 2

Explanation:

Answer. (i) Total potential difference across a combination of resistors in series is equal to the sum of potential difference across the individual resistors. Hence , a fuse of rating 5A can be used because it can bear the current
