Answer: The given circuit diagram is parallel circuit.
Step-by-step explanation:
Resistors are connected in two ways, which result in the formation of two types of circuits. They are:
- Series circuit: In this type of circuit, the resistors are connected end-to-end which results in the formation of single path for the flow of current. The total resistance is always more than the maximum value.
- Parallel circuit: In this type of circuit, the resistors are connected across each other which results in the formation of more than one path for the flow of current. The total resistance is always less than the minimum value.
In the given image, the two bulbs are connected across each other.
Hence, the given circuit diagram is a parallel circuit.
