(CHAPTER 11 – HAND TOOLS AND MEASURING DEVICES) The bevel edge of the thimble is divided into 25 equal parts. Each of these parts represents one twenty-fifth of the distance the thimble travels along the barrel in moving from one of the 0.025 inch divisions to another. Thus, each division on the thimble represents…. One quart of an inch. Twenty fifth hundredth (0.25) of an inch. One one-thousandth (0.001) of an inch. One one-hundredth (0.01) of an inch.

(CHAPTER 11 – HAND TOOLS AND MEASURING DEVICES) In reading a micrometer, the barrel reads 0.275 inch and the thimble reads more than 0.019 inch. The number 1 graduation on the thimble is aligned exactly with the number 4 graduation on the vernier scale. Thus, the final reading is: 0.2944 inch. 0.298 inch. 0.2941 inch. 0.4654 inch.

(CHAPTER 12 – FUDAMENTALS OF ELECTRICITY AND ELECTRONICS) A battery with a capacity of 1 amp-hour should be able to continuously supply a current of 1 amp to a load for exactly 1 hour, or 2 amps for 1⁄2 hour, or 1⁄3 amp for 3 hours, etc., before becoming completely discharged. Actually, the ampere-hour output of a particular battery depends on…. Its specific gravity. Time during which the battery is expected to furnish current. The rate at which it is discharged. The temperature of the electrolyte must be taken into consideration.

(CHAPTER 12 – FUDAMENTALS OF ELECTRICITY AND ELECTRONICS) A field of force exists around a charged body. This field is represented by lines extending in all directions from the charged body and terminating where there is an equal and opposite charge. How do we call this field?. Dielectric field (sometimes called an electric field). Field of force. Electrostatic field (sometimes called a dielectric field). Imaginary lines.

(CHAPTER 12 – FUDAMENTALS OF ELECTRICITY AND ELECTRONICS) What are three types of DC circuit with regard to the placement of the various circuit components?. Series, capacitive, and inductive.
