In the Wein Bridge oscillator circuit shown in figure, the bridge is balanced when |
| A. | \(\frac{{{R_3}}}{{{R_4}}} = \frac{{{R_1}}}{{{R_2}}},\omega = \frac{1}{{\sqrt {{R_1}{C_1}{R_2}{C_2}} }}\) |
| B. | \(\frac{{{R_2}}}{{{R_1}}} = \frac{{{C_2}}}{{{C_1}}},\omega = \frac{1}{{{R_1}{C_1}{R_2}{C_2}}}\) |
| C. | \(\frac{{{R_3}}}{{{R_4}}} = \frac{{{R_1}}}{{{R_2}}} + \frac{{{C_2}}}{{{C_1}}},\omega = \frac{1}{{\sqrt {{R_1}{C_1}{R_2}{C_2}} }}\) |
| D. | \(\frac{{{R_3}}}{{{R_4}}} + \frac{{{R_1}}}{{{R_2}}} = \frac{{{C_2}}}{{{C_1}}},\omega = \frac{1}{{{R_1}{C_1}{R_2}{C_2}}}\) |
| Answer» D. \(\frac{{{R_3}}}{{{R_4}}} + \frac{{{R_1}}}{{{R_2}}} = \frac{{{C_2}}}{{{C_1}}},\omega = \frac{1}{{{R_1}{C_1}{R_2}{C_2}}}\) | |
