Question

34. (a) With the help of a circuit diagram, obtain the relation for the equivalent resistance of two resistan
connected in parallel.
(a) in the circuit diagram shown below, find:
(1) Total resistance
(2) Current shown by the ammeter A​

Answer 1

Answer:there is no diagram bro !!

Explanation:

R = (R₁R₂)/(R₁ + R₂)

or 1/R = 1/R₁  + 1/R₂

V  = I₁R₁  => I₁ = V/R₁

V = I₂R₂  => I₂ = V/R₂

I  = I₁ + I₂

=> I  = V/R₁ +  V/R₂

=> I = V ( 1/R₁  + 1/R₂)

=> 1/ ( 1/R₁  + 1/R₂)  = V/I

=> R = 1/ ( 1/R₁  + 1/R₂)

=> R = (R₁R₂)/(R₁ + R₂)

1/R = 1/R₁  + 1/R₂
