Question

Mark the correct choice as:
Assertion: When the resistances are connected end-to-end consecutively, they are said to
be in series.
Resistance: In case the total resistance is to be increased, then the individual resistances
are connected in series.
a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of
assertion (A).
b) Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation
of assertion (A).
c) Assertion (A) is true but reason (R) is false.
d) Assertion (A) is false but reason (R) is true.
e) Both Assertion and Reason are false.​

Answer 1

Answer:

b) both assertions reason are true and reason is not correct explanation

Answer 2

Both (A) and (R) are true and (R) is the correct explanation of (A). (option a)

• Resistances in a circuit can be connected either end-to-end in series or in separate branches in parallel.
• When connected in series, the effective resistance offered in the circuit is the sum of all the individual resistances connected together- R1+R2+R3+---R(n).
• Hence, the effective resistance increases in the end-to-end series combination.
