Voltage 2 Ohm
1. **Problem Statement:** Calculate the voltage drop across the 2 Ω resistor in the given circuit using the superposition theorem.
2. **Superposition Theorem:** This theorem states that in a linear circuit with multiple independent sources, the voltage/current for any element is the algebraic sum of the voltages/currents caused by each independent source acting alone, with all other independent sources turned off (replaced by their internal resistances).
3. **Step 1: Consider the 24 A current source active, turn off the 6 A source.**
- Turning off the 6 A current source means replacing it with an open circuit.
- The right branch with 6 Ω resistor is open, so no current flows there.
- The 24 A current source and 4 Ω resistor are in series with the 2 Ω resistor.
- Total resistance in this path: $$R_{total1} = 4 + 2 = 6\ \Omega$$
- Current through 2 Ω resistor is 24 A (same as current source).
- Voltage drop across 2 Ω resistor: $$V_1 = I \times R = 24 \times 2 = 48\ V$$
4. **Step 2: Consider the 6 A current source active, turn off the 24 A source.**
- Turning off the 24 A current source means replacing it with an open circuit.
- The left branch with 4 Ω resistor is open, so no current flows there.
- The 6 A current source and 6 Ω resistor are in series with the 2 Ω resistor.
- Total resistance in this path: $$R_{total2} = 6 + 2 = 8\ \Omega$$
- Current through 2 Ω resistor is 6 A (same as current source).
- Voltage drop across 2 Ω resistor: $$V_2 = I \times R = 6 \times 2 = 12\ V$$
5. **Step 3: Combine the effects of both sources.**
- The currents from each source cause voltage drops in the same direction across the 2 Ω resistor.
- Total voltage drop: $$V = V_1 + V_2 = 48 + 12 = 60\ V$$
**Final answer:** The voltage drop across the 2 Ω resistor is $$60\ V$$.
