V = 16.
R = 15000.
Irms = 16/15000.
= 0.001067A,
= 1.067mA.
Im = Irms/0.707.
= 1.067/0.707.
= 1.5mA.

Here, it is (16*1.414)/(15*1000).

Imax= 1.414*irms 1.414*16/15k=1.50ma.

Simple.

Irms = Imax/root(2).

Use this formula.

Emax = 16 V/0.707.

Emax = 22.63 V or 22V.

I = V/R.

I = 22 V/ 15 kΩ.

to convert 15 kΩ to ohms.

15 kΩ * 1000 Ω/1 kΩ.

I= 22 V/ 15000 Ω.

I= 1.46 mA or 1.5 mA.

Vrms\Vavg=form factor=1.1.

Vmax/Vrms=peak factor=1.414.

What is rms?

WKT Vrms = 0.707Vmax => Here Vrms = 16v.

16 = 0.707 * Vmax = >
Vmax = 16/0.707=> 22.6308v.

So, Imax=Vmax / R=> 22.6308/15K = 1.508mA.

Good question about basics.

Vrms = 16v.
Vmax = Vrms*1.414.

Imax = Vmax/r.
Imax = 1.5mA.
