Question
Solve for v1
The image contains an electrical circuit equation commonly found in circuit analysis problems. The equation is as follows: \[ \frac{V_1 - 240}{j10} + \frac{V_1}{50} + \frac{V_1}{30 + j10} = 0 \] ### Explanation: 1. **Terms Involved:** - \( V_1 \) is the variable representing voltage. - \( j \) represents the imaginary unit in electrical engineering, equivalent to the square root of -1. It is used in the context of phasor analysis for alternating current (AC) circuits. 2. **Components:** - The first term, \(\frac{V_1 - 240}{j10}\), represents the relationship of voltage across an impedance of \( j10 \). - The second term, \(\frac{V_1}{50}\), is voltage divided by a resistance of \( 50 \) ohms. - The third term, \(\frac{V_1}{30 + j10}\), indicates voltage across a complex impedance with both resistive (30 ohms) and reactive (j10 ohms) components. 3. **Equation Context:** - The equation is likely set to 0 for balancing purposes, meaning the sum of voltage drops in the circuit equals zero, as per Kirchhoff's Voltage Law (KVL). This type of equation is used to solve for unknown voltages in an AC circuit using complex impedance.
