Why does the load voltage still goes slightly negative with the freewheel diode conntected?
The load voltage can still go slightly negative with the freewheel diode connected due to the inductive nature of the load. When the power supply is turned off, the inductor generates a back EMF, causing the voltage across the load to drop below zero. The freewheel diode allows current to circulate through the inductor, but it may not fully clamp the voltage to zero, especially if there are any parasitic elements or if the diode has a forward voltage drop. As a result, the voltage can momentarily dip into the negative range.

How do you get negative voltage from transformer?
The term, 'negative voltage', refers to its direction and has nothing to do with 'negative' in the 'charge' sense. It's used to indicate the direction in which a voltage is acting in relation to another voltage ('positive' if acting in the samedirection; 'negative' if acting in the opposite direction). So your question is confusing: 'negative' in relation to what?
Does battery voltage combine when you use more than one?
The voltage adds if you connect in series (positive to negative). It stays the same if in parallel (Positive to Positive and Negative to Negative).
What is negative ac voltage?
Negative voltage is voltage that is more negative in polarity than the ground of the circuit.AnswerSince 'voltage' is simply another word for 'potential difference', it can be neither negative or positive in the 'charge' sense! These terms can only be applied to 'potential', not to 'potential difference' (voltage).So, the terms 'positive' and 'negative', when applied to voltage, simply indicate sense or direction in which the potential difference is acting. For example, if you decide that a car battery's voltage is acting in the 'positive' sense in the charging circuit, then the alternator's voltage must then be acting in the 'negative' sense -in other words in the opposite direction to the battery.
Why negative supply is more prefer then positive supply?
A: actually it is the other way around usually negative voltage is a biasing scheme. Most design are begun with a positive voltage in mind. Not that a negative voltage will not work it is just people think positive
What is the special properties of a diode?
in the negative biasing it gives the constant voltage irrespective of limited current.......the voltage it provides in the negative biasing is known as 'zener voltage' due to this property zener voltage is used as voltage regulator........voltage regulator is a circuit which gives constant output even the input is changing.
Is percent voltage regulation can be negative?
yes.. voltage regulation can be negative
What is negative 48 volt DC voltage?
Negative 48 volt DC voltage is simply a voltage that is negative 48 volts with respect to ground. This voltage is widely used in telecommunication systems.

What is the significance of negative values of voltage and current?Negative values show direction and that is the significance
What happens if you connect two batteries of the same voltage positive pole to positive and negative to negative?
If the batteries have EXACTLY the same voltage, then nothing will happen, because there will be no voltage drop in the circuit, and hence no current. If the batteries have SLIGHTLY different voltages, then there will be a voltage drop in the circuit. Since there is low resistance, there might be high current, causing damage and/or an explosion. In all probability, however, there is enough internal resistance in the batteries to simply cause them to equalize in voltage.
Why telephone line has negative voltage?
A negative live voltage is used to prevent electroytic corrosion on the copper wires.

Can Voltage dividers can provide only positive output voltages?
Voltage dividers can provide anything between VCC (the most positive voltage in the circuit) and VSS (the most negative voltage in the circuit). For example, if VCC =0 and VSS = -15, then the output voltage has to be negative. ========================
