7. What will happen to the resistance of a conductor if we reduce its cross- sectional area by a quarter of the original given that the material used was not changed and its length was maintained to the original measurement. * • The resistance will decrease by a factor of 3/4. • The resistance will increase by a factor of 4/3. • The resistance will decrease by a factor of 4/3. • The resistance will increase by a factor of 3/4. 8. In what way should you connect an ammeter to an electronic component to correctly measure the electric current flowing in it? * • Connect it in parallel with the electronic component because current flowing in parallel branches is the same for each branch. • Connect it in series with the electronic component because current flowing in series connections is the same all throughout.
