# Problem 1-14: Current of A Voltage Source

Find the current passing through the voltage source:
a) b) Solution
a) The voltage source is in series with the current source. Since by definition a current source keeps the current passing through itself constant and the voltage source is in series with the current source, it should have the same current $10 A$. b) The same scenario is happening here and the voltage source has the same current as the current source $5A$. Hi! Yaz is here. I am passionate about learning and teaching. I try to explain every detail simultaneously with examples to ensure that students will remember them later too.

1. 2. 3. 4. 5. 6. 1. why in b) 3A current source does not affect in any sense?

1. It has effect on the current of the resistor (=5A+3A). The current of the voltage source is the current of the current source. By definition, a current source keeps the current of the line constant. Any component which is in series with a current source has the same current passing through itself.

What is the effect of the voltage source on the load in b) ???

Thanks

Dear Sir, I have a doubt ..
1. What would be the maximum current that a voltage source can deliver?
Say for eg. what would be the max. current of 230v source
2. Also how that is decided (i mean on what factor)

Also like this i have some basic questions in electrical engg.. where i cud i post them if u have time & willigness to reply?

Thanks,
Pasupathy K.R

in the given circuit is the both the sources are supplying power ? if so what happend if the terminals of voltage source is reversed

Hello sir need help in a similar problem

given circuit

__________ 2A 2 ohm
|Given |-------o ----------------- ( --> )----------^^^^^--------|
| Network | +V ____ 5V
| | - --
|_________ | ------ o--------------------------------------------------|

what would be value of V

If we argue that the current due to current source is constant 2A then i get 9V as the answer ...is this correct.

1. Sorry but the circuit is not clear. What if you take a picture, upload it some where and put link here?
