v=ir
so,
i=v/r
by ohms law.

So here we have v=18.
i=?
r=180
then,
i=18/180
=0.1A.

i.e=100mA.

i=v/r
i=18/180
i=100ma

I = V/R.

I= 18/180= 0.1(option not given).

= 0.1x1000=100 mA.

In dc network inductor coil behave as short circuit. So current (I).

I = V/R.
= 18/180.
= 0.1A or 100mA.

I = V/R.

So 18/180 = 0.1 A or 100 mA.

I=V/R.
=18/180,
=0.1A,
1A=1000mA, SO 0.1A=1000*0.1=100mA.
