Overview
Please complete the following six different circuits on the Tinkercad website. Ensure that each circuit works correctly by clicking the "Start Simulation" button at the top right corner. Once you have finished building them, please send me pictures of your completed circuits.
1. Series Circuit with 2 Resistors
Goal: Learn how components behave when connected in series.
Components: Battery (9V), 2 resistors (e.g., 100Ω), LED, wires.
Setup: Connect the two resistors in series (one after the other) and place them in the circuit. Add an LED in the same path and power it with a 9V battery.
Explanation: In a series circuit, the current flows through each component one after another. You can observe how the voltage is divided between the two resistors and the LED.
2. Series Circuit with 2 LEDs
Goal: Understand how LEDs behave when connected in series.
Components: Battery (9V), 2 LEDs, 1 resistor (e.g., 330Ω), wires.
Setup: Connect two LEDs in series, using a resistor to limit the current. Ensure that both LEDs are oriented correctly, with their anode (+) connected towards the positive side of the battery.
Explanation: In a series circuit, the same current flows through both LEDs, but the voltage is shared between them. This will help you observe how LEDs behave in a series arrangement.
3. Parallel Circuit with 2 Resistors
Goal: Learn how parallel connections work and how the current splits.
Components: Battery (9V), 2 resistors (e.g., 100Ω), wires.
Setup: Connect the two resistors in parallel. This means the two resistors should be connected side by side, with one side connected to the positive terminal of the battery and the other side to the negative terminal.
Explanation: In a parallel circuit, each resistor gets the full voltage of the battery. The current, however, divides between the two resistors. You can observe the differences in behavior compared to a series circuit.
4. Combination Circuit (Series-Parallel)
Goal: Combine both series and parallel connections to see how they work together.
Components: Battery (9V), 1 resistor (e.g., 100Ω), 2 LEDs, wires.
Setup: Set up the first part of the circuit with the resistor and an LED in series, and then add another parallel branch with a second LED. You will have a series part (resistor + LED) and a parallel part (the second LED).
Explanation: In this circuit, you get the benefit of both types of connections. The first LED gets the current flowing through the resistor, while the second LED gets full voltage from the battery in parallel. This will help you understand how different branches work in combination circuits.
5. Voltage Divider Circuit (Series Connection)
Goal: Learn how resistors can divide voltage in a series circuit.
Components: Battery (9V), 2 resistors (e.g., 1kΩ and 2kΩ), voltmeter, wires.
Setup: Connect the two resistors in series, and place a voltmeter across the second resistor. The battery will supply 9V, and the two resistors will divide this voltage.
Explanation: The voltage divider principle demonstrates how the voltage across each resistor is proportional to its resistance. By using a voltmeter, you can measure how the voltage splits between the resistors, which is key for applications like creating reference voltages in circuits.
6. Parallel Circuit with a Switch and Capacitor (RC Circuit)
Goal: Understand how a capacitor charges and discharges in a parallel circuit with a resistor.
Components: Battery (9V), 1 resistor (e.g., 100Ω), 1 capacitor (e.g., 100uF), switch, wires.
Setup: Connect the resistor in series with the capacitor, then place a switch in the circuit to control whether the battery is connected to the circuit. When the switch is on, the capacitor will charge through the resistor.
Explanation: This is an RC circuit (Resistor-Capacitor Circuit), where the capacitor charges and stores electrical energy. When you close the switch, you will see the capacitor charging over time (voltage across it increases), and when you open the switch, it will start discharging. This is important for timing applications in electronics (like filters and timers).
