Complexe transitive verbs explanation

[Jupiter.]

Hullo everybody

I need helping with these sentences.
What is the difference between

I found it difficult to understand. and

I found it's difficult to understand.

Hope to get your help

No, there's really no difference in meaning. In the first one, "found" is used as a "complex transitive" verb, and in the second one it introduces a clause.

Complex transitive verbs are verbs that have two objects, or an object and an adjective, where the two equal each other somehow.

"I found it difficult."
it = difficult

"They elected Mr. Smith president."
Mr. Smith = president

There are other verbs with two objects, and those are called "ditransitive verbs". They have a direct object and an indirect object (the indirect object gets or benefits from the direct object).

"My neighbor gave me a cake."
cake --> me (I got the cake.)

"They stole him a car."
car --> him (He got the car.)

In some sentences a verb can be interpreted as either ditransitive or complex transitive:

"They found Mrs. Johnson a good cook."

This can mean, "They found a good cook for Mrs. Johnson," or, "They found that Mrs. Johnson was a good cook." The meaning is not clear without the context.

Some jokes are based on this contrast between ditranstive and complex transitive:

HOTEL GUEST: "Call me a taxi."
BELLBOY: "Okay! You're a taxi!"

The guest is thinking:

"Call me a taxi."
taxi --> me (I get the taxi.)

The bellboy misunderstands and thinks he is saying:

"Call me a taxi."
me = taxi

I'm sure this is more information than you wanted, but maybe you'll find something in it that you need.
