Description acceptable. Multirange ammeter selector switches may need to operate on the principle of “make-before-[this action].” The maximum power point of a solar cell equals the product of its fill factor, a certain current, and a voltage associated with this action. Power stations quench arcs resulting from this action with sulfur hexafluoride gas. In response to (*) leakage, RCDs perform this action. The I-squared t rating of a certain (0[1])sacrificial component indicates the energy at which it will execute this action by melting. (0[1])Short circuits are typically interrupted by taking this action. For 10 points, fuses are designed to perform what safeguarding action that shuts down a circuit with excess current? ■END■ (10[1]0[1])
