Irms = √(√(i1rms)+ √(i2rms)) Because i1rms=i2rms=3amps.
Irms = √(2√(irms)),
Irms = √(2)*irms,
Irms = 1.414*3 = 4.2a.

Since the given current values are in RMS and the total current to be found in RMS then the total current will be 6 A.

Why are you doing it for max value?

In parallel circuit current are additive.

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

Itrms = 6*0.707.
Itrms = 4.242.

@Savita is right 6A. Answer is in RMS value only no need to multiply 6A by 1.414.

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

Savita said:   1 decade ago
Answer A is right.

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

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

He ask about I total in rms on in I max.

The answer is A.

Sq root of (3^2+3^2) = 3*1.414 = 4.24

Can anyone tell me base of this rule?
