What does negative voltage and negative current mean?

In the case when a voltage source has negative voltage, it just means the negative terminal of the battery is connected to the positive side of the circuit and the positive terminal of the battery is connected to the negative side of the circuit .

Does negative current exist?

Yes, negative potential and negative current exist. Negative potential: Objects having excess supply of electrons (-ve charge) is said to be having negative potential.

Is the electric potential negative if yes then explain how it can be?

Electric potential is a property of the field itself, so, if the charge is negative, the electric potential of a test charge is negative at any point besides when the test charge is infinitely far away, in which case it would be zero.

What if the current is negative?

Originally Answered: What does it mean if current is negative? If a current measurement is negative, it means the current is flowing in the direction opposite to that which is expected.

What does the negative current mean?

Negative current is current flowing in the opposite direction to positive current, just like the axes on a graph have negative and positiva in opposite directions. A sensor that can read negative and positive current could be used to mesaure rate of charging or discharing a battery.

What is meant by negative potential?

: an electric potential lower than that of the earth or other conductor taken as an arbitrary zero of potential.

Can the potential difference be negative?

As you step across the circuit elements in the same direction as the current in the element, the potential difference can be positive or negative. As there is no energy accumulation in the circuit, the increases in potential difference must be equal to the decreases in potential difference.

Do negative potential and negative current exist?

Yes, negative potential and negative current exist. Objects having excess supply of electrons (-ve charge) is said to be having negative potential. In day to day life, we people refer the potential by term “voltage”.

What is negnegative potential?

Negative potential is just a potential that has attractive nature. If you see Earth’s potential, it is negative as it is attractive. If you study potential of electrons in atom, you will find it to be negative. The positively charged nucleus attracts the negatively charged electrons.

What is the difference between positive and negative current in DC?

Answer Wiki. In case of DC, Positive means higher voltage and negative means lower voltage, current flows from higher potential to lower potential. positive side has deficiency of electrons while the negative side has excess of electrons. actually current is the flow of electrons which flows from negative to positive terminal.

What does a positive potential difference VAB mean?

In this case a positive potential difference Vab simply means that difference of potential between point A and B is positive and thus point A is at higher potential than point B.
