point 8

7) Is it possible to have a zero electric field value between a negative and positive charge along the line joining the two charges? A) Yes, if the two charges are equal in magnitude.

PROBLEM 2 – 15 points The electric potential from a single charge is defined to be zero an infinite distance from the charge, and the electric potential associated with two charges is also defined to be zero when the charges are infinitely far apart.

The electric potential at point A is 3137.46 V.

Electric potential of a point charge is V=kQ/r V = k Q / r . Electric potential is a scalar, and electric field is a vector. Addition of voltages as numbers gives the voltage due to a combination of point charges, whereas addition of individual fields as vectors gives the total electric field.

• Work done on charge? No.
• Electric PE is greatest at: A. (When a + charge moves naturally in the direction of the E field, it is moving from high PE to low PE.
• Electric potential is greatest at: A. (For the same charge, the electric potential is greatest at locations of higher potential energy.)

The electrical potential difference is defined as the amount of work done to carrying a unit charge from one point to another in an electric field. In other words, the potential difference is defined as the difference in the electric potential of the two charged bodies.

Electrical potential is the energy per unit charge gained or lost when a charge is moved from some reference point at which the potential is defined to be zero. Voltage is the difference in potential between two arbitrary points at which the potential is not necessarily zero.

In the case of static electric fields, the voltage between two points is equal to the electrical potential difference between those points. Voltage, also sometimes called potential difference or electromotive force (EMF), refers to the amount of potential energy the electrons have in an object or circuit.

electric potential energy

Voltage is electric potential difference between any two points in the circuit. Volts are units which describes that electric potential difference between two points in the circuit.
