Activity 1: WHICH IS WHICH? Direction: Given that all other factors are equal, the current will be greatest in a circuit that has a. a high resistance ................................................... a low resistance b. wires that are long ................................................ wires that are short c. wires that are wide ................................................. wires that are thin d. 12-gauge wires [1/12th inch diameter} or 14-gauge wires (1/14th inch diameter) e. copper wiring ........................................................ silver wiring Activity 2: PROBLEM SOLVINGI Direction: Solve each problem. Show complete solution in a separate sheet of paper. 1. What is the resistance of a 30 in silver wire with a 2 mm diameter? 2. A carbon wire with a 3 mm diameter has a resistance of 100 ohms. How long is the wire? 3. A 200 m long aluminum wire has the same resistance and cross-sectional area as a carbon wire. What is the length of the carbon wire? 4. A wire made of an unknown substance has a resistance of 125 mg. The wire has a length of 1.8 rn and a cross-sectional area of 2.351105 m2. What is the resistivity of the substance from which the wire is made? Give your answer in scientific notation to one decimal place 5. Differentiate Ohmic from no-Ohmic materials. 6. Differentiate emf ofa source and potential diiference (PD) across a circuit Erection: Complete the table below. Use another sheet of paper for your answer. Laws of Rattan\" What will happen to the resistance? 1. Law of Length 2. Law of Diameter 3. Law of Nature of the material 4. Law of Temperature
