Basic 12V DC Motor Circuit Simulation - Switch Open, 15A Fuse & Multimeter Test

This document is a screenshot of a computer-simulated electrical schematic (drawn in circuit-simulation software such as Multisim) illustrating basic switch operation in a simple DC circuit. The circuit consists of a 12-volt battery (V2), a single-pole switch (J1, actuated by keyboard key 'A'), a 15-amp fuse (U1, labeled 15_AMP), and a DC motor armature load (S1, labeled DC_MOTOR_ARMATURE), all connected in series. A multimeter instrument (XMM1) is connected across the switch to measure electrical values during simulation. Wire nodes are numbered 1 through 4. In this view (filename 'SWTCH OP.jpg'), the schematic depicts the switch in the open position, part of a training set that includes companion images showing the switch closed, amperage, source voltage, fuse, and test-voltage readings. A reader can learn how a basic automotive-style circuit (battery, switch, fuse, motor) is arranged in series and how a meter is placed to test voltage across an open switch. The document is generic educational material and contains no vehicle-specific fuse charts, wire colors, connectors, or part numbers; it does not state any year, make, or model applicability.
