What is the current flow in 230v ac supply ? What is the current flow in 415v Ac supply ?..

Answer / naveen

it depends up on the load connected and if same load is
conneted then the current flow in single phase is root
three times more.

What is the current flow in 230v ac supply ? What is the current flow in 415v Ac supply ?..

Answer / abhishek0015

It depends upon connected load. As per formula,
P= V*I*(cos phi)-- for 230v supply and
P= sqrt3*V*I*(cosphi)-- for 415v supply
So it means in 230v single phase supply takes almost 3
times more current than 415v three phase supply.

What is the current flow in 230v ac supply ? What is the current flow in 415v Ac supply ?..

Answer / arpit

it will be the same since 230volt ac and 415 volt ac are
star connected, in star VL=1.732* vph, and current is same.

What is the current flow in 230v ac supply ? What is the current flow in 415v Ac supply ?..

Answer / srujanya,rec

By taking the OHM's Law i.e. V=IR. here we consider R is
constant then V is directly proportional to I. it means If
Voltage increases then current also Increases. in 230V ac
supply gives 23A. In 415V ac 41.5A flows(R=10 ohms)

What is the current flow in 230v ac supply ? What is the current flow in 415v Ac supply ?..

Answer / prabhu

current is load connected in the supply.
If same amount of load was connected in single phase and
also in three phase ,the cuurent taken by single phase is
of 3 times more than the three pahse.

What is the current flow in 230v ac supply ? What is the current flow in 415v Ac supply ?..

Answer / samit sinha

As mentioned by Srujanya, V=IR is wrong it should be I =
V/R because current is proportional to Coltage and not
voltage is proportional to current. When the potential
difference occurs then only current flows - Samit
