Question

State the law of combination of resistances in parallel.

Answer 1

Answer:

Law's of Combination of Resistance connected in parallel state that resultant Resistance of the Resistors connected in parallel with the sum of Their Reciprocal, of their individual Resistances

Resistance is basically an abstraction offered by the material in movements of electrons now these resistance can be combined in two ways ...one is series connection and other is parallel connection

1 = 1 1 1

___ ____ _____ _____

R R1 , R2 R3

Hope it's helpful for you....

Answer 2

Explanation:

• The law of combination of resistances in parallel states that the combined resultant resistance of the resistors connected in parallel is equal to the sum of the reciprocal of their individual resistances.
• It means the potential difference across two ends of each resistor is same.
• So, let us consider resistors R1, R2, R3 and R4 are connected in parallel.
• Therefore, according to the law of combination of resistances in parallel, the resultant resistance,  $\text {RResultant}=\frac{1}{R 1}+\frac{1}{R 2}+\frac{1}{R 3}+\frac{1}{R 4}$
