Series and Parallel Circuits
Series Circuit
In the Tinkercad program, a series circuit with 5 resistors of different values was built on a virtual breadboard. These values were manually assigned, keeping the multiplier of each resistor constant in orange (1000Ω). The circuit was connected as follows:
Then with the virtual multimeter the total resistance of the circuit was found and the result was checked with the sum of all the resistors.
Electrical Voltage
Then a 9V battery was connected to the circuit and the total voltage was checked with the virtual multimeter, connecting it as shown in the picture:
Voltage for Each Resistor
Then the electrical voltage of each resistor was found with the virtual multimeter as shown in the following image.
Circuit Current
Finally the current of the circuit was found with the virtual multimeter.
Series Circuit Calculations - Ohm's Law
To check the values previously found with the multimeter, the following calculations were made according to Ohm's Law.
The value of the electric current in series circuits is the same in all components because in a series circuit, the components are connected one after the other. This means that the same current flows through all. The reason for this can be explained by Kirchhoff's Law of Currents, which states that the total current flowing into a node in a circuit must be equal to the total current flowing out of that node.
Parallel Circuit
As in the previous circuit, in the Tinkercad program, a parallel circuit with 5 resistors of different values was built in a virtual breadboard. These values were assigned manually. The circuit was connected as follows:
Then with the virtual multimeter the total resistance of the circuit was found and the result was checked with the sum of all the resistors.
Electrical Voltage
Then a 9V battery was connected to the circuit and the total voltage was checked with the virtual multimeter, connecting it as shown in the picture:
Current for Each Resistor
Then the electrical current of each resistor was found with the virtual multimeter as shown in the following images.
Circuit Current
Finally the total electric current of the circuit was found.
Parallel Circuit Calculations - Ohm's Law
In a parallel circuit, all the elements or receivers are connected directly to the same voltage source, which means that they are at the same voltage.
