Answer:
In the series circuit the current I through all the resistors is same. This means that any of the resistor is not open and the current through each will be same as through R2. Ohm's law as gives the voltage across the resistor as
V = R*I
As voltage across R2 is non-zero, a current is there through R2. This implies that there must be the same current through the whole circuit of through every resistance, and hence the voltage across all resistances must be non-zero.
But we see that there is no voltage shown across four resistors, this may ...
