Question

explain parallel resistance and formula​

Answer 1

Explanation:

parallel combination of resistance the current is divided into many parts and voltage is same then we take I .

1/R= 1/Rn

if there's only two resistance then

R=R1×R2/R1+R2

Answer 2

Answer:

if resistors are connected parallel then the total current flowing through the circuit is

I = I1 + I2+.. ........ (i)

let Rp be the effective resistance

according to ohms law

I = V/Rp

similarly

I1 = V/R1 , I2 = V/R2 ,....

substituting these in equation (i)

V/Rp = V/R1 + V/R2....

therefore

• 1/Rp = 1/ R1 + 1/R2..
• note

the potential difference remains the same
