V = IR voltage drop in a resistor is directly proportional to resistance value.

Please, anyone explain.
What is mean by voltage drop?
Is Voltage drop means a decrease in voltage or increase?

As we know in a series circuit. Current is same so the amount of voltage drop totally depends upon resistance. As per the rule V = IR, so MORE THE RESISTANCE more will be voltage.

Explanation:
Simple logic is that, Consider 1 amp current and calculate vtg drop across each resistance you will find that the more value resistance has more voltage drop.
V = IR.
4.7*1 = 4.7.
12*1 = 12 .
2.2*1 = 2.2.

When ever resistances are connected in series, same current flows hence more the voltage drop more the value of resistance according to ohms law i.e., V proportional to R.

We know current in all resistors of a series circuit is same.
By Ohm's Law we know,
V=IR.
Or, V is proportional to R.
So, drop will be higher where R is higher.
So, max voltage drop occur across 12 ohm resistor.
