An engineer is testing a 12 V DC miniature solenoid actuator, represented by the rectangular block S S\,S in the incomplete circuit diagram below.
To determine the operating resistance of the actuator, the engineer must measure:
- the electric current passing through the actuator,
- the potential difference across the actuator.
Complete the circuit diagram by adding the correct circuit symbols for an ammeter and a voltmeter connected in the correct positions to allow both measurements to be taken simultaneously.
