  • 1. Manaoag National High School Manaoag, Pangasinan First Departmental Test TLE – Metalcraft Grade VIII NAME: _____________________________________ YEAR & SECTION: _______________ I. MULTIPLE CHOICE Direction: Encircle the letter of the best answer. This is a discipline in the field of engineering and applied science which deals with the design and application of devices which are usually composed of electrical circuits. a. Basic Electronics b. Basic Electricity c. Basic Computer The rate of flow of electrical charge, the movement of electrons or ions through a conductor. a. Voltage b. Current c. Resistance Electrical Pressure measured in volts which causes current to flow through an electrical conductor. a. Current b. Voltage c. Resistance This is a property of conductors measured in ohms. a. Resistance b. Current c. Voltage This is the rate at which work is done. a. Power b. Resistance c. Current What electronics tool is used for stripping the insulation of stranded wire ends. a. Diagonal full flush plier b. Long nose plier c. Wire stripper Used to remove excess or unwanted soldering lead from the board. a. Pen knife b. Desoldering tool c. Flat file This electronics tool is used for intermittent soldering of electrical components a. Soldering iron/gun b. Glue gun c. Blowtorch Test instrument is used to measure small current flowing in a given circuit component. a. Ohmmeter b. Voltmeter c. Milliameter II. TRUE OF FALSE Direction: Write true if the statement is correct and false if the statement is wrong. __________1. The long nose plier is used to cut metal sheets. __________2. The tip of the soldering iron should be washed properly. __________3. The pen knife is used for stripping insulation from wires. __________4.
