Question

The equivalent resisIstance of a series comBination of two resistance is X . If the resistance are of 10 ohm and 40 ohm the value of X will be * 2 points 10 ohm 20 ohm 50 ohm 40 ohm

Answer 1

Answer:

40 +10 50 ohm will be the equivalent resistance of the circuit.

Answer 2

$\large{\bf{\gray{\underline{\underline{\orange{Given:}}}}}}$

Two identical resistors (10Ω and 40Ω) are connected in series.

Equivalent resistance of the series combination = x

$\large{\bf{\gray{\underline{\underline{\green{To\:Find:}}}}}}$

We have to find the value of x.

$\large{\bf{\gray{\underline{\underline{\pink{Solution:}}}}}}$

Equivalent resistance of the series combination is given by

$:\implies\tt\:R_s=R_1+R_2$

$:\implies\tt\:x=10+40$

$:\implies\underline{\boxed{\bf{\red{x=50\Omega}}}}$

Equivalent resistance of the parallel combination is given by

$\dag\:\boxed{\bf{\purple{\dfrac{1}{R_p}=\dfrac{1}{R_1}+\dfrac{1}{R_2}}}}$

፨ Potential difference across each resistor remains same in parallel connection.

፨ Current flow through each resistor remains same in series connection.
