AC Voltage Divider

The two impedance voltage divider is used often to supply a voltage different from that of an available AC signal source. In application the output voltage depends upon the impedance of the load it drives. This calculation makes use of the complex impedance method and the expressions for parallel impedances. This type of calculation is used to set up an AC Thevenin equivalent for network analysis.

For impedances Z1 = + j Z2 = + j driven by voltage 由电压驱动 V1 = V, the open circuit output voltage would be 开路输出电压将是 Vout = + j V V_out = +j V 中文译文中的待填/计算数值依次对应：1：v2 2：v2x。实际数值以上方原输入框为准。 Vout = V at degrees. 输出电压等于在度数下的电压。 中文译文中的待填/计算数值依次对应：1：v2a 2：v2p。实际数值以上方原输入框为准。 关于阻抗 中文译文中的待填/计算数值依次对应：1：r1 2：x1 3：r2 4：x2 5：v1。实际数值以上方原输入框为准。

If this voltage divider is supplying a load 如果这个电压 divider 正在为负载供电 ZL = + j then the output circuit voltage is 则输出电路电压为 Vout = + j V V_out = +j V 中文译文中的待填/计算数值依次对应：1：v3 2：v3x。实际数值以上方原输入框为准。 Vout = V at degrees. 输出电压等于在度数下的电压。 中文译文中的待填/计算数值依次对应：1：v3a 2：v3p。实际数值以上方原输入框为准。

Note: To avoid dealing with so many short circuits, divider resistors with value zero will default to 1 when the voltage is changed and the load will default to 1000. They can be changed back to a zero value if you wish to explore the effects of short circuits. Ohms are indicated as the resistance unit, but kilohms are more common and of course the calculation is the same.
