gbaby370 said:I just completed a problem regarding a Millikan Oil Drop Experiment. I ended up with a negative voltage in the solution.
I am just trying to understand negative voltage. Does it mean that the current will travel from - to + instead of the conventional + to -?
phinds said:yes it does
Waterfox said:If the "-" represents the ground or reference then I believe the "+" can have any potential difference whether positive or negative. In such a case though the "-" terminal will have the higher potential and so conventional current will run from it to the "+" terminal.
Negative voltage is a measure of electrical potential energy that is opposite in direction to the flow of current. It is usually represented by a negative sign and is commonly used in circuits to control the direction and flow of electric current.
Current travels in negative voltage by flowing from a point of lower potential energy to a point of higher potential energy. In circuits, this is typically from the negative terminal to the positive terminal of a battery, or from a negative voltage source to a positive voltage source.
Negative voltage has several applications in modern technology. It is commonly used in electronic circuits to control the direction and flow of current, in power supplies to regulate voltage levels, and in telecommunications to transmit and receive signals.
Negative voltage is measured using a voltmeter, which is a device that measures the difference in electrical potential between two points. The negative voltage is typically measured in volts (V) and is represented by a negative sign.
Negative voltage can pose potential dangers if not handled properly. It can cause electrical shock, short circuits, and damage to electronic devices. It is important to follow proper safety precautions when working with negative voltage to avoid accidents and injuries.
