There is a fixed voltage across a resistor, and you measure a current of c1 A. If you replace the resistor with one that has twice the resistance value, how much current will you measure? a) 0.2 A b) 0.5 A c) 0.8 A d) 1.1 A

Option B

Explanation:

Given

The current flowing through the circuit = 1 Ampere

As we know

I is inversely proportional to resistance.

I α 1/r

or I = k/r

If the resistor "r" is replaced by any resistor "R" with resistance = 2r, then the current will be

I = 1/2 of 1 ampere

I = 0.5 Ampere

Hence, option B is correct

your answer is c! hope this : )
