What is the need of using combination of resistance in electrical circuits? Define equivalent resistance. |
|
Answer» SOLUTION :Combination of resistances is used in circuit so as to get the desired value of current in an electrical circuit. i] SERIES combination ii] Parallel combination iii] Series-parallel combination. Equivalent resistance: If a SINGLE resistance can replace the combination of resistances in such a MANNER that the current in the circuit remains UNCHANGED, then that single resistance is called the equivalent resistance. |
