Edexcel A-Level Physics Field Lines and Equipotentials

Practise Edexcel A-Level Physics field lines and equipotentials by drawing radial and uniform fields and interpreting test-charge motion.

Exam points

draw radial field lines with correct spacing and arrow direction for positive or negative charges
draw uniform field lines and equipotentials between parallel charged plates
interpret whether field lines show force, acceleration or the path of a positive test charge

A spark chamber consists of a set of parallel metal plates. It can reveal the path of a high energy particle as shown.

A potential difference of 10.5 kV is applied across two adjacent plates as shown below.

Sketch lines to represent the electric field between the plates.
