Compute and sketch vo and iR for the network given below.
Understand the Problem
The question is asking to compute the voltage (vo) and current (iR) for a given electrical network and to create a sketch representing these values. This involves analyzing the circuit and potentially applying circuit theory concepts.
Answer
The specific computed values of $v_o$ and $i_R$ depend on the values of circuit elements provided.
Answer for screen readers
To fully answer your question, specific values for the circuit components (resistances, voltage sources) are needed. However, based on the steps given, you will derive values for voltage and current from the circuit analysis.
Steps to Solve
- Identify the Circuit Elements
First, identify all the components in the circuit given. Note down resistors (R), voltage sources (V), and any current sources (I). Make sure you understand how these components are connected (in series or parallel).
- Apply Ohm's Law
For calculating voltage ($v_o$) across a resistor, use Ohm's Law, which states:
$$ V = I \times R $$
where $V$ is the voltage, $I$ is the current, and $R$ is the resistance.
- Calculate Total Current ($i_R$)
If the circuit has multiple resistors, use series and parallel rules to find the total resistance $R_{total}$:
- For resistors in series: $$ R_{total} = R_1 + R_2 + ... + R_n $$
- For resistors in parallel: $$ \frac{1}{R_{total}} = \frac{1}{R_1} + \frac{1}{R_2} + ... + \frac{1}{R_n} $$
- Use Kirchhoff's Laws
Apply Kirchhoff’s Voltage Law (KVL) to analyze the loops in the circuit and solve for the unknowns. The sum of the voltages around any closed loop in a circuit must equal zero.
- Sketch the Circuit with Calculated Values
Create a simple sketch of the circuit, labeling all components clearly. Include the computed values of $v_o$ and $i_R$ on the sketch.
To fully answer your question, specific values for the circuit components (resistances, voltage sources) are needed. However, based on the steps given, you will derive values for voltage and current from the circuit analysis.
More Information
When calculating voltage and current in a circuit, it's helpful to visualize the components through a sketch, which makes it easy to understand the relationships. Circuit theory relies on several key principles, including Ohm's Law and Kirchhoff's Laws, to solve for unknown values.
Tips
- Not properly identifying whether resistors are in series or parallel, which can lead to incorrect resistance calculations.
- Forgetting to account for all voltage sources in the circuit when applying KVL.
- Mislabeling circuit elements in the sketch, leading to confusion.
