science physics# How do resistors behave in series and in parallel?

Last Updated: 12th March, 2020

**resistor**in a

**series**circuit has the same amount of current flowing through it. Each

**resistor**in a

**parallel**circuit has the same full voltage of the source applied to it. The current flowing through each

**resistor**in a

**parallel**circuit is different, depending on the resistance.

Moreover, what happens when resistors are connected in parallel?

**Resistors** in **parallel** - When **resistors are connected in parallel**, the supply current is equal to the sum of the currents through each **resistor**. When **resistors are connected in parallel**, they have the same potential difference across them.

Subsequently, question is, why current is same in series? In a **series** circuit, the **current** flowing through the circuit elements is **same**. But the voltage drop across each element depends upon the value of resistance or reactance. The resistance opposes the flow of **current** through it.

One may also ask, how do you calculate resistors in parallel and series?

To **calculate** the total overall **resistance** of a number of **resistors** connected in this way you add up the individual resistances. This is done using the following **formula**: Rtotal = R1 + R2 +R3 and so on. Example: To **calculate** the total **resistance** for these three **resistors** in **series**.

Is voltage the same in parallel?

A **parallel** circuit has two or more paths for current to flow through. **Voltage** is the **same** across each component of the **parallel** circuit. The sum of the currents through each path is **equal** to the total current that flows from the source.
