Resistors are electrical components used to control the flow of electricity through a circuit. Adding more resistors to a parallel circuit will reduce the total resistance of the circuit. The total resistance of a series circuit is the sum of all the resistors. Adding parallel resistances to a series circuit will reduce the total resistance of the circuit but increase the total current. This is because lower resistance equals higher current.

**Resistors control the flow of the electric current in a circuit**

In a circuit, two or more resistors are connected in series. In a series circuit, the voltage across each resistor is different. If one of these resistors breaks, the circuit is terminated. This construction is more straightforward and less complicated than a parallel circuit.

In parallel circuits, the voltage across all the resistors is equal. The charge does not accumulate at any single point. This makes it possible to have more than one path in parallel circuits. The total current in a circuit with parallel and series elements will be the same.

Parallel and series circuits are both similar in their fundamentals, but they differ in some ways. The difference between the two is the way that the components are connected. In parallel circuits, the components are connected one after the other along parallel branches. Because of this, each resistor contributes to the total resistance of the circuit. In a series circuit, the resistors are connected in a line. Therefore, the total resistance in a series circuit is the sum of all individual resistances.

As you can see, a parallel circuit is simpler than a series circuit. It consists of the same components as a series circuit, but the branches are connected side by side. A parallel circuit has the same voltage and current, but the resistance can vary between the branches.

**Differences between series and parallel connections**

In series connections, the electric current flows through all elements. The number of elements in a series connection is the same as the number of elements in a parallel connection. In parallel connections, the starting and finishing points of each element are connected to a common point. Thus, the equivalent resistance of a series connection is larger than that of a parallel connection.

Series and parallel connections have the same power supply, but the current flowing through the resistors is higher. In series connections, the current flowing through a resistor equals the current in the source. In parallel connections, the resistance in the connecting wires is much smaller. This means that the power supplied to each device is equal to the total power dissipated.

Parallel and series connections are both types of electrical connections, but each has its own special properties. In series connections, the parts are connected across one another, while in parallel connections, the parts are connected end to end. Neither of these methods has a fixed voltage, but both are commonly used for various applications. In the home, the difference between series and parallel connections is in the way in which they combine.

In a series circuit, a single component may have a fault, but it will not affect other components. In parallel connections, a single fault in one component may lead to a complete failure of the system. Hence, a parallel connection is easier to detect and repair than a series circuit.

In a parallel circuit, each component is connected in parallel, so that the current can flow through all components simultaneously. This makes the system easier to troubleshoot. For example, in parallel connections, all appliances in a home are connected in parallel, so that each one doesn’t affect the other.

When connecting components in a series circuit, the total resistance of each device is the same. In parallel connections, the total resistance is greater, but the voltage is lower than it is in a series circuit. The current flowing through a series circuit is equal to the voltage supplied by the battery. This type of circuit is referred to as current-coupled or daisy chain.

Series circuits have more components than parallel ones, but the total resistance is higher. Therefore, the flow of current is more constant than in a parallel circuit. This also increases the probability of a burnout in a series circuit. Parallel connections are more durable than series connections. But in case of a short, one component can fail and disrupt the whole circuit.
