Series Circuit
In series circuit, components are connected end to end in line to form a single path for electron to flow. Hence the current throughout the circuit will be same. If any of the component is disconnected or removed, then circuit becomes open and no current flows in the circuit. The circuit below illustrates the series circuit.
In the above circuit positive is connected to the first component(R1) and negative is connected to the last component(R3). Since all the three components are connected in series, current through all the components are same. But voltage across each components varies.
In the below image the component R2 is removed, so the circuit becomes open and there is no current flow in it.
Parallel Circuit
In parallel circuit, components are connected across each other like a branch. It makes many path for electrons to flow but voltage across all the branches are same. Even if any of the component is removed, the current through the other components continues to flow.
In the above circuit all the components are connected across each other, which makes several nodes. The positive supply is commonly connected to all the components and negative supply also commonly connected to all the components. Here each components makes individual closed circuit, so current flow through each component varies.
In below image even if the component R2 is removed, the other components remains closed and current continues to flow.
Things To Remember
Series Circuit
1. Current throughout the circuit same
2. Voltage across each component varies
3. If any of the component is removed, then no current flows in the circuit.
Parallel Circuit
1. Voltage across each components are same.
2. Current through each component varies.
3. Even if any of the components is removed, current continues to flow to the other components.
