Answer the following statement(s) true (T) or false (F)
1. To measure the wattage of a circuit, a meter must have two coils; one coil is affected by the magnetism and one by the resistance.
2. One of the most common methods used to accurately measure values of resistance, inductance, and capacitance is with a bridge constructed by connecting four components together to form a parallel-series circuit.
3. Many digital meters have voltage range settings from 20 millivolts to 200 volts, and the higher ranges are used for accuracy.
4. Digital ohmmeters measure resistance by measuring the amount of voltage drop across an unknown resistance.
5. An ohmmeter must never be connected to a circuit when the power is turned on.
