I = V/R.
V = 7v.
R = 1k.
I = (7-0.7)/1000 = 0.007{The forward voltage drop for Silicon diode is 0.7v}.
{The forward voltage drop for Germanium diode is 0.3v}
i.e I = 6.3/1000 = 6.3mA.
V = 7v.
R = 1k.
I = (7-0.7)/1000 = 0.007{The forward voltage drop for Silicon diode is 0.7v}.
{The forward voltage drop for Germanium diode is 0.3v}
i.e I = 6.3/1000 = 6.3mA.

I=V/R,
where V=V-Vsi,
Vsi=0.7V and V=7V
R=1K ohm = 1000ohm.
So, I=(7-0.7)/1000.
=6.3/1000,
I = 6.3 mA.
where V=V-Vsi,
Vsi=0.7V and V=7V
R=1K ohm = 1000ohm.
So, I=(7-0.7)/1000.
=6.3/1000,
I = 6.3 mA.

Yes, voltage drop must be considered because here series term is used.
