Voltmeter aur Ammeter(ampere meter)ke connection ko samjhe,CT aur CT ratio,rotary selector switch

1-voltmeter=To see the voltage between any two lines or lines and neutral,3 phase and 1 phase The connection-connect voltmeter in parallel with the source of power, ie single-phase line or 3 phase line 2-Ammeter=TO see the ampere of any load, ampere in one phase and 3 phases The connection-connect ammeter in series with the load queries solved:- 1-Digital and Analog type voltmeter and Ammeter 2-3 phase voltmeter,1 phase voltmeter 3-3 phase ammeter 1 phase ammeter 4-CT(Current Transformer ) kya Hota hai, Kaise Kam Karta hai 5-CT ratio kya Hota hai,ct Kaise select Karte hai, 6-Rotary selector switch for voltmeter and ammeter 7-how to do the connection of these selector switches to see the 3 phase voltages and currents Energymeter connection https://youtu.be/_iX7zlfEEyw Relay holding https://youtu.be/9wUM4AriolI Solid state relay holding https://youtu.be/KgF2m_bRH6E Auto reverse forward with sensors https://youtu.be/laKc3fPaJws Inching and holding of contactor https://youtu.be/vCCzjyWDpDI Auto transformer starter control wiring https://youtu.be/w4KLm-kZ86c 2 floor lift wiring animation video https://youtu.be/b1sqkowY4R4 Gate open close wiring https://youtu.be/yzaWd-NZm50 Pump motor and float switch wiring https://youtu.be/UkC3W_lpHxQ Compressor pressure switch wiring star delta starter https://youtu.be/wCVW38hKK3c Compressor pressure switch wiring https://youtu.be/-mZFMtS8U_o 3 floor lift wiring simulator video https://youtu.be/unM1lOQZkug Delta vfd f parameter setting https://youtu.be/RSM-o8vqKQo Delta vfd f control and power wiring https://youtu.be/MDXB5iWT1Zo What is maximum demand md https://youtu.be/nCQ7ppZdrPU Multiplication factor https://youtu.be/w6-AZ2TJ97Y Counter meter connection with sensors https://youtu.be/FT4FETaRE_k Check sensors is npn or pnp https://youtu.be/KYBt-gwZZT4 Delta vfd run using push button https://youtu.be/J7_meZPKqSU #VOLTMETER #AMMETER #CT #RATIO
