Answer :
To effectively use a digital multimeter, it's important to understand its various settings and functions. The Ohms setting on the multimeter is specifically used for two primary purposes:
Measuring Resistance:
- The Ohms setting allows you to measure the resistance in an electrical circuit. Resistance is measured in units called ohms (Ω), and it tells you how much a device or material opposes the flow of electric current. This is crucial in checking the health of components like resistors in a circuit. If a resistor is not providing the expected resistance, it may be faulty or damaged.
Continuity Test:
- The Ohms setting is also used for performing continuity tests. A continuity test checks if a complete path for current exists in a circuit. When using this mode, the multimeter will typically emit a beep if the circuit is closed (i.e., has continuity), indicating that electricity can flow freely. This is particularly useful for checking fuses, switches, and connections between wires.
Given these functions, the correct answers to the question are A. Measuring resistance and C. Continuity test.
Keep in mind that other functions like measuring voltage (B. Voltage drop test) and measuring current (D. Measuring amperage draw) use different settings on the dial, typically labeled as V for voltage and A for amperage, respectively. Each setting on a multimeter is crucial for diagnosing and troubleshooting electrical systems safely and effectively.
