What are some of the features of today's engine analyzer systems?

Technician A says that in a series circuit, the same current flows through each resistance. Technician B says an ammeter must be connected in series. Who is correct?

While discussing Ohm's law formula: Technician A says the resistance (R) is calculated by dividing the amperes (I) into the volts (E). Technician B says the amperes (I) are calculated by dividing the resistance (R) into the volts (E). Who is correct?

On a digital multimeter, 60 millivolts may be displayed as 60.0 mV or 0.060 V.
