Question

In the circuit shown in fig. $E subscript 1 end subscript equals 3 V comma E subscript 2 end subscript equals 2 V comma E subscript 3 end subscript equals 1 V comma R equals r subscript 1 end subscript equals r subscript 2 end subscript equals r subscript 3 end subscript equals 1 o h m$ Find the potential difference between the points A and B and the currents through each branch.

$2 V, I_{1} = I_{2} = I_{3} = 0$
$5 V, I_{1} = I_{2} = I_{3} = 0$
$2 V, I_{1} = I_{3} = 1 A, I_{2} = 0$
$2 V, I_{1} = 1 A, I_{2} = 2 A, I_{3} = 3 A$

The correct answer is: $2 text end text V comma I subscript 1 end subscript equals I subscript 3 end subscript equals 1 text end text A comma I subscript 2 end subscript equals 0$

The gap between two plane plates of a capacitor equal to d is filled with a gas. One of the plates emits $n subscript 0 end subscript$ electrons per second, which moving in an electric field, ionize gas molecules, this way each electron produces $alpha$ new electrons (and ions) along a unit length of its path.
