1. The size of wire need to power an elictrical oven is ___ gauge wire.

The correct answer is 8 because the gauge of a wire determines its thickness and ability to carry electrical current. In the case of powering an electrical oven, which typically requires a high amount of power, a thicker wire with a lower gauge, such as 8 gauge, is needed to handle the load and prevent overheating or voltage drop.

2. What is a king stud

A supporting beam under the house

Full-height studs on either side of a window or door opening

Mr. King

A king stud refers to the full-height studs that are positioned on either side of a window or door opening. These studs provide additional support and stability to the structure around the opening, ensuring that the frame remains strong and secure. This helps to distribute the weight of the structure evenly and prevent any sagging or damage over time. Therefore, the correct answer is full-height studs on either side of a window or door opening.

3. In wiring where in the stud should you drill your holse at?

1 1/4" from the front edge of the stud

3/4" from the back edge

1/4" from center

Stay back from the front edge of the stud 1 1/4", or drill the center of the stud. If you can't get the 1 1/4" clearence, then you will have to install nail plates, like the ones plumbers use to protect their pipes.

4. Why size of nail do you commonly use in framing

16d

14d

18d

12d

The commonly used nail size in framing is 16d. This size is preferred because it provides enough strength and holding power to secure framing members together. The "d" in 16d stands for "penny," which is a unit of measurement for nails. The number 16 indicates the length of the nail, which is 3 1/2 inches. This length is suitable for attaching thicker pieces of wood commonly found in framing structures.

5. In residential grade wiring, what wire gauge do you use the most.

12,2

14,2

18,2

12,3

The correct answer is 14,2 because it refers to a wire gauge commonly used in residential grade wiring. The gauge number represents the thickness of the wire, with a lower number indicating a thicker wire. In residential wiring, 14-gauge wire is often used for general lighting and outlet circuits. The "2" refers to the number of conductors or wires within the cable, which is typically used for hot and neutral wires. Therefore, 14,2 is the most commonly used wire gauge in residential grade wiring.

6. Find the current in a 120 volt, 90 watt circuit?

24 amps

.24 amps

10800 amps

.75 amps

The current in a circuit can be calculated by dividing the power (in watts) by the voltage (in volts). In this case, the power is given as 90 watts and the voltage is given as 120 volts. Dividing 90 by 120 gives us 0.75 amps, which is the correct answer.
