ou are an electrician on the job. You have been given a multimeter that has the following AC voltage ranges: 30, 60, and 150. The meter states that it has a resistance of 5000 Ω /V. You need to be able to measure a voltage of 277 volts. How much resistance should be inserted in series with the meter to make the 30-volt range indicate a full scale value of 300 volts?

leaving a freevway. Current from the opposite side must travel further, weakening the potential on that side. This creates a potent the motor in that direction, causing the motor to spin. O Only the side where the switch is closed forms a cormplete circuit, so the motor must spin in that direction.
