What device combines functions of measuring voltage, current, and resistance?

• A. Ammeter
• B. Ohmmeter
• C. Multimeter
• D. Voltmeter

Answer: (C)

A multimeter is a versatile device that combines the functionality of measuring voltage, current, and resistance into one instrument. This multi-functional capability makes it essential for electricians and technicians when troubleshooting electrical circuits. When using a multimeter, one can easily switch between measuring different electrical parameters, which is particularly helpful in various applications ranging from simple home wiring assessments to complex electronic diagnostic tasks. Its design allows for easy readings and often includes features such as digital displays and additional testing functions like diode testing and continuity checks. In contrast, the ammeter is specialized for measuring current, the voltmeter for measuring voltage, and the ohmmeter for measuring resistance. Although each of these devices serves a specific purpose, only a multimeter encompasses all three functions, thereby providing a comprehensive tool for various electrical measurements.
