We’ll use! Measuring Voltage = is DC ~ is AC Measure across a component. Switch Battery Resistor Light
We’ll use! Measuring Current = is DC ~ is AC Circuit flow must go through the meter. Switch Battery Resistor Light
We’ll use! Measuring Resistance = is DC ~ is AC Measure across the component being tested. Power must be off or removed from the circuit. Switch Battery Resistor Light
