Answer : The correct series circuit is, (D)
Explanation :
Parallel circuit : In this circuit, the potential across each of the components are same but the current flow in the circuit is equal to the sum of the current flow of each components.
That means in this circuit, the potential across the circuit is same but current is different.
[tex]I=I_1+I_2+I_3[/tex] where, 'I' is current.
Series circuit : In this circuit, the current flow each of the components are same but the potential across the circuit is equal to the sum of the potential of each components.
That means in this circuit, the current flow across the circuit is same but potential is different.
[tex]V=V_1+V_2+V_3[/tex] where, 'V' is potential.
From the given circuits, the circuit D is the series circuit. while the other circuits are parallel circuits.
Hence, the given circuit (D) is a type of series circuit.
