Question

draw thevenins equivalent circuit and find volatage acrosa Rl for tye given circuit​

Answer 1

Answer:

Refer 4 IMAGE 01

Applying KVL

10 - 5i - 20i = 0

i = 2/5 * A

.. V eq =V AB =20i=8 V

To find R eq short the battery

Refer IMAGE 02

R eq =R AB = 20*5 20+5 =4 Omega(As 5 Omega and 20 Ω are parallel across AB)

Equivalent circuit:

Refer IMAGE 03

Applying KVL

8 - 6i - 0

=> i= 4/3 A

V L =iR L = 4 3 *2=2.66 V.

Answer 2

This is your right answer.

Hope it will help you..
