Can the work done by an electric field be negative?
It can be either positive or negative. If the charged object speeds up, the electric field is doing positive work. If it slows down, the electric field is doing negative work. When the work is done by field there is decrease in potential energy in moving charge from one point to another.
Why should electric field lines never cross?
Electric field lines cannot cross. … This is because they are, by definition, a line of constant potential. The equipotential at a given point in space can only have a single value. If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.

In most cases, pipe or rebar can be used. The grounding rod needs to be made of galvanized steel and also needs to be at least four feet in length for best results. Using copper rods will diminish the overall effectiveness of the electrical fence system.
Why is my sunbeam electric throw blinking?
The controller will blink red if the throw is disconnected or the internal heating wires have broken (open circuited). For me it went back into normal operation once I had reconnected the throw to the controller then reset it by unplugging the AC power plug then plugging it back in.
