interface
The friction that two surfaces excert on each other when they rub against each other is called a friction.
Capacitance
node Any number of currents can meet at a node, not just two.

The same it always do - provides a seal between two surfaces.
The point where two surfaces meet is called an "intersection" or a "junction."
The point at which two surfaces come together is called a junction or an intersection. This can create a seam or a joint, depending on how the surfaces are connected.
... are straight lines where two planar surfaces meet.

When in reference to architecture, arris refers to the sharp edge formed when two curved or flat surfaces meet. The surfaces must meet at a salient angle.
When two surfaces intersect, they form a line of intersection, which is the set of points where both surfaces meet. This line can be straight or curved, depending on the nature of the surfaces involved. The intersection is significant in geometry and calculus, as it can define boundaries or regions in three-dimensional space.
The space between two lines or surfaces that meet is called the "angle" if it refers to the measure of rotation between them, or "gap" if it refers to the physical distance separating them. In geometric terms, angles are typically measured in degrees or radians. If the surfaces are not intersecting, the term "clearance" might also be used to describe the space between them.
The friction that two surfaces excert on each other when they rub against each other is called a friction.
Angle is a space between two lines or surfaces that meet at one point, which you measure in degrees.
