Example: co-axial cable. Any two charged conductors form a capacitor. A wire is a conductor, so it is an equipotential. Capacitors in parallel have SAME potential difference but NOT ALWAYS same charge. = Q = Q (WHY??) Q2 What is the charge on each capacitor? What is the potential difference across each capacitor?
For a point charge, equipotential surfaces would be spheres with the charge at the center. At any given point the equipotential lines are always perpendicular to the electric field lines. The surface of a charged conductor in equilibrium is an equipotential surface since the electric field is everywhere perpendicular to the surface.
A wire is a conductor, so it is an equipotential. Capacitors in parallel have SAME potential difference but NOT ALWAYS same charge. = Q = Q (WHY??) Q2 What is the charge on each capacitor? What is the potential difference across each capacitor? In the circuit shown, what is the charge on the 10μF capacitor?
This means that equipotential surfaces around a point charge are spheres of constant radius, as shown earlier, with well-defined locations. Two large conducting plates carry equal and opposite charges, with a surface charge density σ σ of magnitude 6.81 × 10−7 C/m2, 6.81 × 10 − 7 C/m 2, as shown in Figure 7.37.
An equipotential sphere is a circle in the two-dimensional view of Figure 7.30. Because the electric field lines point radially away from the charge, they are perpendicular to the equipotential lines. Figure 7.30 An isolated point charge Q with its electric field lines in red and equipotential lines in black.
This implies that a conductor is an equipotential surface in static situations. There can be no voltage difference across the surface of a conductor, or charges will flow. One of the uses of this fact is that a conductor can be fixed at what we consider zero volts by connecting it to the earth with a good conductor—a process called grounding.
