Voltage check karne ke liye aapko kuch basic tools ki zarurat hoti hai. Yahan main aapko step-by-step guide dunga:

1. **Multimeter:** Yeh device voltage, current aur resistance measure karne ke liye use hota hai. Aapko ek multimeter ki zarurat hogi jo voltage measure kar sakta ho.

2. **Safety:** Electrical work mein safety bahut zaroori hai. Voltage check karne se pehle, sure ho jayein ke power off hai aur aapke paas insulation wala equipment hai.

3. **Steps to check voltage:**

   - **Multimeter select karein:** Multimeter ko voltage mode par set karein. Typically, yeh DC voltage (direct current) aur AC voltage (alternating current) modes mein measure kar sakta hai.

   - **Probes connect karein:** Multimeter ke red probe ko positive terminal aur black probe ko negative terminal par connect karein.

   - **Voltage check karein:** Agar aap AC voltage check kar rahe hain, toh phase wire (jisse voltage check karna hai) aur neutral ya ground ke beech mein probes lagayein. DC voltage check karne ke liye positive aur negative terminals par probes lagayein.

   - **Reading dekhein:** Multimeter screen par voltage reading display hogi. Is reading se aap voltage level determine kar sakte hain.

4. **Interpretation:** Voltage readings typically volts mein di jaati hain. AC voltage gharo mein usually 120V ya 240V hoti hai (depending on your location), jabki DC voltage alag-alag appliances ke liye vary karta hai.

Voltage check karte waqt hamesha sure ho jayein ke aapke multimeter ki range voltage se zyada na ho, warna multimeter damage ho sakta hai. Aur electrical work mein always safety measures follow karein. Agar aapko electrical work karne mein confidence nahi hai, toh ek professional electrician se help lein.
