Explain how oiling would affect the efficiency of the wind turbine __ (d) In most homes in the UK there are many different electrical devices Explain why people should be encouraged to use energy efficient electrical devices __

Multimeter Auto Range Most multimeters have an auto range function. This function causes the meter to determine the right scale automatically. Simply set the selector switch to the "auto" position, then connect the measuring probes to the inputs. This function has one disadvantage. Because the meter determines the scale on its own, there's a slight delay in processing.In the event of a sudden change in voltage it may take a couple seconds before a reliable reading is displayed This means there's a chance you could take an inaccurate reading while the meter is transitioning to the appropriate scale. 1 The picture opposite shows a multimeter connected across a lamp with a poor contact. The contact breaks every now and then. The multimeter is set to the auto range position. What happens? The value on the meter does not change The decimal point moves across the display. The value fluctuates between 0 and 12V

1 Answer each question. Please note: you can answer each question only once. When you've answered a question, you can go to the next question. You can scroll back to see your answers. Good luck! (1) What is a disadvantage of the autorange function on a multimeter? When the voltage changes only the minimum value is displayed. When the voltage changes , only the maximum value is displayed. When the voltage changes , it takes a little while before a reliable voltage reading is displayed.
