What makes a uniform electric field

There are some tricky experiments in this topic, and it is well worth practising them in advance. Teaching Guidance This episode introduces the above three quantities for the electric field. Lesson This episode introduces fields, field lines and equipotentials in the context of electric fields. Much of this is revision Electric Field. Activity time 70 minutes Level Advanced. Download this episode Episode - Uniform electric fields.

Appears in these Collections Ready To Teach Collection Electrical fields Students will have first come into everyday contact with electric field phenomena My charged objects setup is just like the two panels setup. I don't get why two-panel setup gets to have uniform electric field.

While mine cannot do such a thing!? Show 1 more comment. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password. Post as a guest Name.

Ionization created by the particles as they pass through the gas between the plates allows a spark to jump. The sparks are perpendicular to the plates, following electric field lines between them.

The potential difference between adjacent plates is not high enough to cause sparks without the ionization produced by particles from accelerator experiments or cosmic rays. Since the electron is a single charge and is given Entering this value for V AB and the plate separation of 0.

The force on the charge is the same no matter where the charge is located between the plates. This is because the electric field is uniform between the plates. In more general situations, regardless of whether the electric field is uniform, it points in the direction of decreasing potential, because the force on a positive charge is in the direction of E and also in the direction of lower potential V. Furthermore, the magnitude of E equals the rate of decrease of V with distance.

The faster V decreases over distance, the greater the electric field. In equation form, the general relationship between voltage and electric field is. The minus sign tells us that E points in the direction of decreasing potential. The electric field is said to be the gradient as in grade or slope of the electric potential. The electric field strength between the plates is 2. Skip to main content.
