g Old-style dimmers consisted of a variable resistor so you could dial in more resistance to lower the current and, hence, dim the light. If the increased total resistance caused the current to be reduced by 50%, then by what percent would the power dissipation be reduced

To protect all four receptacles on a branch circuit that surrounds a swimming pool, you would install which of the following configurations? a. gfci feed-through receptacle at the end of the load's circuit b. gfci-terminated receptacle at the beginning of the load's circuit c. gfci feed-through receptacle at the beginning of the load's circuit and the other receptacles connected to the load side of that receptacle d. gfci-terminated receptacle at each end of the load's circuit
