When a load is connected to the output voltage divider the output voltage will what?
When a load is connected to the output of a voltage divider, the output voltage will typically decrease due to the loading effect. This occurs because the load draws current, which can change the voltage across the resistors in the divider. The extent of the voltage drop depends on the resistance of the load relative to the resistors in the voltage divider. If the load resistance is significantly lower than the divider resistances, the output voltage will drop more noticeably.

Why a low value of load resistance has significant effect on the voltage gain of a common-source amplifier?
A low load resistance in a common-source amplifier can significantly reduce the overall voltage gain because it introduces a larger voltage drop across the load, decreasing the output voltage. The voltage gain (Av) is influenced by the load resistance (RL) since it is part of the voltage divider formed with the output resistance of the transistor. When RL is low, the effective output impedance decreases, leading to a lower gain. Additionally, a low load resistance can also increase the output current, potentially driving the amplifier into a nonlinear region, further affecting gain stability.
What is a voltage divider circuit?
The voltage divider circuit is a network of two or more components in series, often resistors, between a potential difference. The voltage between the components will be somewhere between the potential difference across the whole network and so divides the total voltage into one or more intermediate voltages.
When the RL changes how does this affect the Nortons or Thevenins equivalent circuit?
When the load resistance (RL) changes, it affects the Norton or Thevenin equivalent circuit by altering the output voltage and current delivered to that load. For a Thevenin equivalent, the output voltage can change based on the voltage divider effect, while for a Norton equivalent, the output current will vary according to the current division principle. This means that the values of the equivalent voltage source (Vth) or current source (In) remain constant, but the load will experience different voltage and current levels depending on its resistance. Consequently, the overall power delivered to the load will also change.
What is the effect of change in load resistance on output voltage?
No.
What is the off load voltage of the generator?
Terminal voltage is the voltage between the output terminals of a generator.
What is the current that flows through an unloaded voltage divider?
The current that flows through an unloaded voltage divider is very small, close to zero. This is because there is no load connected to the output of the divider, so there is nowhere for the current to flow. The purpose of a voltage divider is to divide the input voltage between the two resistors, not to pass current.
What is voltage divider circuit?
The two resistor voltage divider is used often to supply a voltage different from that of an available battery or power supply. In application the output voltage depends upon the resistance of the load it drives.
If all the resistors in a voltage divider circuit are doubled the output voltage will be half?
No, the output will remain constant. If you double all the values, the divider ratio will not change, and it is the ratio that determines the output voltage. The current flow through the divider itself will change, it will be half the original value. This could affect the accuracy of the divider. For the same accuracy, the minimum load resistance would be double the original value.

What is the definition of stiff voltage divider?
Well, honey, a stiff voltage divider is basically a circuit that divides a voltage into two parts with minimal variation, even when there are changes in the load. It's like the Regina George of voltage dividers - it stays stable and doesn't let anything shake it up. So, if you want a reliable way to divide your voltage without any drama, a stiff voltage divider is the way to go.
What is the purpose of a zener diode when placed near the output in a common power suplly?
The purpose of a zener diode connected at the output of a common supply is to stabilize the output voltage in case a load is connected to it.
How does the load affect voltage output of a series generator?
In a series generator, the voltage output is directly affected by the load. As the load increases, the voltage output decreases due to increased voltage drops across the internal resistance of the generator. Conversely, reducing the load will result in an increase in the voltage output.
Can you test the output amps of a DC generator with no load?
Any voltage source, whether a generator or a battery, will NOT supply an output current unless it is connected to a load. So the only way to test the output current is by connecting it to a load.

What is the output when a secondary voltage of 24V is connected to bridge rectifier when no load is connected?
24VACRMS * 1.414 = 33.94VACPEAK The unloaded filtered DC voltage is 33.94V The unloaded unfiltered voltage will be a single polllarity AC voltage with a peak of 33.94V

What is the load side of a transformer?
The load side of a transformer feeds the device, such as a light or motor. It is the output of the transformer. The input, or line side, provides the voltage that is to be transformed, either up or down, to supply the load side.AnswerA transformer's primary winding is connected to the supply voltage, and the secondary winding is connected to the load.
