Two equipotential lines cannot cross. These lines are perpendicular to the electric force, and the electric force at a point in space can only point in one direction. Equipotential lines can be considered to be similar to the contour lines on a map, which also never cross.
Another way in which the equipotential lines are similar to contour lines on a map is when considering work done by a force. An object traveling along an altitude contour line would not have to do work against the force of gravity. Similarly, equipotential lines are perpendicular to the electric force, so charges that travel along the equipotential line do not need to do any work against the electric force.Learn More
The cross-sectional area of a wire is the size of the face of the wire if it was cut vertically perpendicular to it's length. The cross-sectional area is independent of wire length and is typically uniform across the entire length.Full Answer >
Electric field lines are drawn around charges to represent the direction as well as the strength of the field around the charges. Equipotential lines are drawn perpendicular to each electric field line and connect the electric field lines at points where their field strengths or potential difference are equal.Full Answer >
Two common types of circuits are series and parallel. An electric circuit consists of a collection of wires connected with electric components in such an arrangement that allows the flow of current within them. A series circuit has no branches but instead has several components arranged one after the other.Full Answer >
The two main types of energy are kinetic energy and potential energy. These energy types are both conserved, which means that neither energy type is created or destroyed. Instead, kinetic and potential energies are transformed into each other.Full Answer >
