# Educational Content on Circuit Analysis and Kirchhoff’s Rules ## Visualization **Instructions:** - Draw the circuit in the space provided. - Record the measurements of your last circuit design and calculate the % error associated with each resistor in the circuit. ### Resistor Measurements #### R₁ value: _______ Ω | Measurement | Theoretical | Experimental | % Error | |-------------|-------------|--------------|---------| | I (mA) | | | | | V (V) | | | | #### R₂ value: _______ Ω | Measurement | Theoretical | Experimental | % Error | |-------------|-------------|--------------|---------| | I (mA) | | | | | V (V) | | | | #### R₃ value: _______ Ω | Measurement | Theoretical | Experimental | % Error | |-------------|-------------|--------------|---------| | I (mA) | | | | | V (V) | | | | ## Kirchhoff’s Rules **Question:** What is the current in the 10Ω resistor? Is the current going right to left or left to right? ### Circuit Diagram Explanation: - The circuit contains three resistors: 5Ω, 10Ω, and another 5Ω. - There are three voltage sources: 12V, 3V (connected in reverse), and 9V. - The 12V and 9V batteries are shown in series with one 5Ω and one 10Ω resistor. - The 3V battery is connected across the 10Ω resistor, indicating a direction which may influence the current flow through it. ### Analysis: Analyze the circuit using Kirchhoff’s Voltage and Current Laws to find the direction and magnitude of the current through the 10Ω resistor. Consider the effect of each voltage source and resistor on the circuit's current distribution.

**Tasks to Accomplish** Design circuits that demonstrate all of the principles listed below. Set up the circuits and take measurements to show that the principle in question is indeed correct. **Principles of Series Circuits** 1. The sum of the voltages across each circuit element equals that of the battery. 2. The current through each circuit element is the same. 3. Resistors with higher resistances have higher voltages across them. 4. Resistors added in series to any circuit increase the total resistance to current in the circuit. **Principles of Parallel Circuits** 1. Voltages across each circuit element are the same. 2. The sum of the currents through each parallel circuit element equals the current through the battery. 3. Resistors with higher resistances have less current through them. 4. Resistors added in parallel to any circuit decrease the total resistance to current in the circuit. **General Principles** 1. A branch in a circuit that contains a short has no voltage across it. 2. A branch in a circuit that is open has the full voltage across it. 3. A battery is a constant voltage source. 4. A battery is not a constant current source. 5. Ammeters have very small internal resistance. 6. Voltmeters have very large internal resistance.
