What is a Series Circuit?
A Series Circuit is a circuit in which the current has a single path to flow.
Calculating a Series Circuit:
We can calculate voltage, resistance and current across a Series Circuit using Ohm's law & then check the calculations using a multimeter. Here are the steps:
- Draw the Series Circuit showing voltage and resistors.
- Draw a table with columns for all the resistors, voltage, impedance (current) and their total.
- First, calculate the total resistance using the following formula:
- Next we will calculate the total current using Ohm's law.
The answer will be in Amperes. We can multiply the answer by 1000 to make it milliamperes.
- Calculate the voltage across each resistor using Ohm's Law:
- Calculate current across each resistor using Ohm's Law:
Conclusion:
In a Series Circuit, the Voltage is divided but the Current remains the same.
Verification:
You can test your calculations by using a multimeter on a real circuit or it's simulation in Tinkercad.
