sq root of(3sq=3sq)=4.24

Can anyone explain this?

Vaibhav said:   1 decade ago
Sq root of (3^2+3^2) = 3*1.414 = 4.24

Can anyone tell me base of this rule?

According phasor diagram of current of parallel R-L circuit.

Answer A is right.

Irmstotal = IRrms+ILrms.
Itotal = 3+3 = 6 A.

Tejeas said:   1 decade ago
@Savita is right 6A. Answer is in RMS value only no need to multiply 6A by 1.414.

Please confirm the answer anyone.

In parallel circuit current are additive.

It = I1+I2.
It = 3+3.
It = 6.

Itrms = 6*0.707.
Itrms = 4.242.

6A since the type of load won't matter for parallel current distribution.
