Case Study on Advance Course NEET-AIIMS Physics Syllabus Current Electricity
Case Study: Analysis of a Series Circuit
Let’s consider a case study that demonstrates the application of the advanced course NEET-AIIMS Physics syllabus for current electricity. In this case, we will analyze a series circuit consisting of resistors and a capacitor.
Problem Statement: A series circuit consists of a 12V battery, a 6Ω resistor, an 8Ω resistor, and a 100μF capacitor. Calculate the total current flowing through the circuit, the voltage drops across each component, and the time constant of the RC circuit.
Solution: To solve this problem, we will apply the concepts and formulas covered in the NEET-AIIMS Physics syllabus for current electricity.
Step 1: Calculate the total resistance (R_total): R_total = R1 + R2 = 6Ω + 8Ω = 14Ω
Step 2: Calculate the total current (I_total): Using Ohm’s law, we can calculate the total current: I_total = V_total / R_total = 12V / 14Ω ≈ 0.857A
Step 3: Calculate the voltage drop across each component: Using Ohm’s law, we can calculate the voltage drops across the resistors: V1 = I_total * R1 = 0.857A * 6Ω ≈ 5.14V
V2 = I_total * R2 = 0.857A * 8Ω ≈ 6.86V
The voltage drop across the capacitor will be equal to the battery voltage since the capacitor is uncharged initially: Vc = 12V
Step 4: Calculate the time constant (τ) of the RC circuit: The time constant (τ) can be calculated using the formula: τ = R_total * C = 14Ω * 100μF = 0.0014s
Conclusion: In the given series circuit, the total current flowing through the circuit is approximately 0.857A. The voltage drop across the 6Ω resistor is about 5.14V, and the voltage drop across the 8Ω resistor is approximately 6.86V. The voltage across the uncharged capacitor is 12V. The time constant (τ) of the RC circuit is calculated to be 0.0014s.
