When Is the Hopscotching Technique Used?

Hopscotch, a fast finite difference technique, is used to solve parabolic and elliptic equations in two space dimensions with a mixed derivative. The method is compared numerically with existing alternating direction implicit (A.D.I.) and locally one dimensional (L.O.D.) methods for simple problems.

Why is hopscotching important tool in troubleshooting?

An excellent method of troubleshooting an electrical circuit is to use a procedure referred to by some technicians as “hopscotching.” This method allows a technician to easily determine the electrical status of a control switch.

When replacing fuses Be sure to match which of these ratings?

When replacing a fuse, always follow the manufacturer's specifications or match the amperage of the fuse that you're replacing. Never use a fuse with an amp rating greater or less than that of the circuit wiring. For example, do not use a 20-amp fuse on a circuit with 15-amp wiring.
