Ohm law V = IR.

V = 110V, I=3.5A, R=?,
R = V/I,

R = 110/3.5,
R = 31.42857142857143,
R = 31 OHM.

By using for OHMS law.

Given:

R = V/I.

So, R = 110/3.5 = 31.42.

Answer: 31 OHM.

V = IR.
R = V/I.
Given V = 110 V, I= 3.5 A.

R = 110/3.5 = 1100/35 = 22O/7 = 31.42~31.

Make calculations easy.

In accordance with ohm's law, current through DC circuit is given by I = V/R.

Here we want to know the value of hating material, that is R.

Since I and V is given so the value of R is given by R = V/I.

That is 110/3.5 which is 31.4.

Yes according to Law I = VR.

V = 110 V, I = 3.5 A & R=?

There fore we want Resistance so that R = V/I.

R = 110/3.5.

R = 31.42 or R = 31 Ohm.

V = IR.

110 = 3.5*R.

R = 110/3.5.

R = 31.42 [CUT OFF].

R = 31.

Absolutely right 110/3.5.

31.428 ohms.

According to ohm's law voltage is directly proportional to current in a specified conductor having some resistance.

i.e V = RI.

I = V/R.
I = 110/3.5.
I = 31.4 A.

V = RI.
I = V/R.
I = 220/3.5.
I = 31.4 A.
