ACCORDING TO OHM'S LAW,
R(resistance)=V(voltage)/I(current)
=12/3.6
=3.33 kilo-ohm

Ohm's Law :- V = I*R

But here we adjust the terms as,
R = V/I
= 12/3.6 * 10^-3 ...(^ sign is POWER )
= (12/3.6)* 10^3 ...(shifting of 10^-3)
= 3.3 * 10^3
R = 3.3 kilo-ohm

I want range of mA and killo-ohm. Any one say?

Surekha said:   1 decade ago
mA=10^-3
kilo ohm =10^3

V=I/R
V=12/3.6
V=3.3KM

Nice answer vinay

Absolutely its 3.33kilo ohms.

I=V/R
V=12V
I=3.6mA=3.6*10^-3
R=V/I
R=(12/36*10^-4)Ohm
=(1/3)*10^4ohm
=0.333*10^4ohm
=3.33*10^3ohm
=3.33kilo-ohm

V=12, I = 3.6mA=0.0036A.

V=IR.

R=V/I=12/0.0036=12*10^4/36=10^4/3=10000/3=3333.33 ohm.

3.3 kilo ohm.

V=12
I=3.6mA
R=12/3.6*10^-3=12/0.036=3.3kohms.
