Which of these is the same in identical branches of a parallel circuit? A) All of these.B) Voltage.C) Current.D) None of theseE) Resistance.
again my textbook says that voltage is the one that the paths are the same,is it all of these?
B) Voltage
This is what I thought too (found in my textbook) it is teling me it is wrong!!
The current is the same in each branch AND the voltage is the same down each branch.
in identical branches A) All of these
(U = IR )
post it.
In a parallel circuit, the branches are connected in such a way that the voltage across each branch is equal. So the correct answer would be B) Voltage.
To understand why voltage is the same in identical branches of a parallel circuit, we can look at the basic principles of parallel circuits. In a parallel circuit, each component has the same voltage across it because all branches are connected directly across the same two points (i.e., the terminals of the power supply). This means that the voltage is distributed equally across each branch.
To confirm this, you can also apply Ohm's Law. Ohm's Law states that the voltage (V) across a component is equal to the current (I) passing through it multiplied by its resistance (R), mathematically represented as V = I * R.
Assuming the branches in the parallel circuit are identical, which means they have the same resistance, and the current entering the parallel circuit is divided equally among the branches, we can see that the voltage across each branch will be the same, as the resistance and current are the same.
So, ultimately, in identical branches of a parallel circuit, the voltage is the same (answer B), but the current, resistance, and all of these (answer A) are not necessarily the same for each branch.
