select all the correct answers. which circuits are parallel circuits?
Answer
Answer:
The third and fourth circuits are parallel circuits.
Explanation:
Step1: Recall parallel - circuit definition
In a parallel circuit, components have their own separate paths for current flow and the voltage across each component is the same.
Step2: Analyze first circuit
The first circuit has components connected one - after - another in a single path, so it is a series circuit.
Step3: Analyze second circuit
The second circuit also has components connected in a single path, so it is a series circuit.
Step4: Analyze third circuit
The third circuit has three resistors connected in parallel as they have separate paths for current flow and share the same voltage source, so it is a parallel circuit.
Step5: Analyze fourth circuit
The fourth circuit has two branches with light - bulbs. Each branch is a separate path for current flow and they share the same voltage provided by the battery, so it is a parallel circuit.
