Answer:
A longer answer would be: following Ohm's Law, I= E/R where E (voltage) is the potential difference being kept constant, and doubling the resistance, you would get 1/2 as much current in the circuit.

Answer:
V=ir
R=v/I so here we can see that are is inversely proportional to the R therefore If R get doubled then I reduce to half
Plz mark me as brainliest
