Question

Mention any two important precautions to be taken while measuring the
equivalent resistance for the combination of two resistors in series or parallel.

Answer 1

Answer:

1.connection should be tight

2. You must have to use equal length and equal cross sections resistor

Answer 2

Answer:

The first thing to be focused  on is the constant terms in series and parallel combinations

Explanation:

in series combination the current remains constant across the circuit , where as in parallel combination voltage remains constant.Then from using V=iR we can easily calculate the equivalent resistanc of circuit.
