What is the formula for Greg?
Is Electrical force (Coulomb) conservatives?
Closed line integral = 0
What is electrical potential difference?
What is the formula for electrical potential difference?
Where do we set our reference point for electrical potential energy?
What do we mean by potential at a point
It is the difference between that point and reference point (0)
What is electrical potential?
What is equipotential surface?
What is the angle between electrical field and equipotential surface?
Orthogonal
What is the equipotential contours for uniform electrical field?
What is the equipotential contours for electrical charge?
What is the equipotential contours for two opposite electrical charges?
As you get closer to a positive charge → does the potential energy increase or decrease
Increase (test charge) → work done against the field to place the test charge closer to the positive charge
As you get closer to a negative charge → does the potential energy increase or decrease
Decrease (test charge) → work done by the field to get test charge closer to the negative charge
How to get the electrical potential difference from electrical field?
Will the electrical potential difference differ if you take different path (same initial and final point)
No
What is the electrical potential due to a point charge?
How to you add multiple electrical potential?
As scalars
What is the electrical potential due to a electric dipole
Draw a energy graph of an electric dipole
How do you find electrical field from electrical potential?
What is the formula for electrical potential energy?
How does positive charge and negative charge behave in the same electrical field?
What is the electrical potential and electric fiend inside and outside a conductor
Why does charge build up at sharp edges?
Are the equipotential contour evenly spaced in a capacitor?
Yes
What is the formula for charge in a capacitior?
What is the formula for parallel plate capacitance?
What happens if you stack alternating electric plate for capacitor?
How will the capacitance be if you roll the plates?
What is the formula for spherical capacitance?
How do you add capacitors in series?
What is the formula for the sum of capacitor in parallel?
What is the formula for energy stored in a capacitor?
What is the formula for energy charge density?
What happens if the dielectric does not fill up the whole capacitor?
What is dielectric strength
