1. The problem statement, all variables and given/known data

2. Relevant equations

Anyone Know why If an ideal voltage source and an ideal current source are connected in parallel, then the combination has exactly the same properties as a voltage source alone?

and If an ideal voltage source and an ideal current source are connected in series, the combination has exactly the same properties as a current source alone?

3. The attempt at a solution

Why don't you have a go at sharing your thoughts on the matter. Start by stating the characteristics of ideal voltage and current sources.

well.. the truth is i'm not even sure what is ideal current voltage and ideal current source. all i know is ideal voltage source is a voltage source that won't drop because of some internal resistance (which is impossible) and ideal current source.. i'm not sure of it.

Since the problem depends upon knowing what these two items are, it might be best if you check your text first.

i had. but scientific english is too difficult for me. my country's primary language isn't english. i thought someone can help me simplify it in this forum

An ideal voltage source will produce ANY amount of current necessary to maintain its rated voltage. (No matter how the load is varied, it will maintain that voltage)

An ideal current source will produce ANY amount of voltage necessary to maintain its rated current. (No matter how the load is varied, it will maintain that current)

Needless to say, it's not a good idea to short circuit ideal voltage sources, nor is it a good idea to open-circuit ideal current supplies; In either case something's going to go BOOM!
