Abstract
A resistive structure has an improved electric field profile deposited on the surface of a cylindrical insulating substrate. At least one resistive path or trace is provided with a helix-looking shape and is directly printed on the surface of the insulating substrate. A resistive voltage divider includes first and second resistors electrically connected in series, where each resistor is made of one or more traces of electrically resistive film material applied onto a cylindrical insulating substrate. At least one of the traces is shaped like a helix and is applied onto the substrate by direct printing.
