Question

If three resistors $5\Omega ,6\Omega \&8\Omega$ are connected in series.The effective resistance is ...............

• A. 24$\Omega$
• B. 240$\Omega$
• C. 7$\Omega$
• D.
  • 19$\Omega$

Answer 1

The correct option is D

• 19$\Omega$

Given: Resistance 1 = 5 ohm

Resistance 2 = 6 ohm

Resistance 3 = 8 ohm

Solution: When the resistors are connected in series the equivalent resistance of the circuit is given by,

$R_{eq}=R_1+R_2+R_3...$

So, according to question the equivalent resistance will be given by,

$R_{eq}=5+6+8$

$R_{eq}=19\Omega$

Hence, the correct option is (D).
