What is the direction of the electric field within the cell membrane?
The direction of the electric field is always from higher electric potential to lower electric potential, so the direction of electric field for the cell membrane is towards inside the living cell.
What is the electric potential at points AB and C?
FREE Expert Solution The electric potential at points A, B, and C in the figure is 1800V, 1800V, and 900V, respectively. b. P.E = (9 × 109)(2.0 × 10-9)(-1.602 × 10-19) /(1.0 × 10-2) = – 2.88 × 10-16 J.
What is the electric field strength inside the capacitor What is the potential energy of a proton at the midpoint of the capacitor?
The potential energy of a proton at the midpoint of the capacitor is 2.4 × 10-17J.
What is the potential energy of a proton that is half way between the two plates?
What Is The Potential Energy Of A Proton That Is Half Way Between The Two Plates? 3o0v 3.0 M.
What is the magnitude of the force on a Proton at the midpoint?
F=qE. Where, E is the magnitude of the electric field at the point where the charge q is placed. Thus, the magnitude of the electric force on a proton at point P (midpoint) is: F=qpEnet≈(1.602×10−19C)(1.0×104N/C)≈1.6×10−15N.
Does current flow from lower to higher potential?
Answer Expert Verified Electric current flows from a higher potential to lower potential. When a circuit is connected using conductors, an electric field is established in the direction towards lower a potential point from a higher potential point.
Why is a positive terminal at higher potential?
Answer: Yes, conventionally we represent the positive terminal always as higher potential. The electric conductor having excess of electrons is said to be at a negative or lower potential and the conductor having deficit of electrons is said to be at a positive or higher potential.
Why is potential difference measured in parallel?
Measuring potential difference To measure the potential difference across a component, a voltmeter must be placed in parallel with that component in order to measure the difference in energy from one side of the component to the other. Potential difference is also known as voltage and is measured in volts (V).
