Question

How to double the current without changing voltage

Answer 1

Answer:

reduce the resistance to half

Answer 2

By ohm's Law

V = iR

where, V = Voltage

i = Current

R = Resistance

So, keeping V constant

i = V/R

2i = V / R/2

So, we can decrease the resistance by half to increase the current by two times without changing the Voltage.

So, R = R/2

Hope it helps.
