Question

Circuit taken a current 5A at 100v what value of resistance be added in series with circuit limit the current to 2A

Answer 1

STEP BY STEP EXPLANATION

By using Ohms law i.e. V=IR

we have given V= 100v & I= 5A

so, R=v/i => R=100/5 => 20 ohm

value of R when I=2A

R=100/2 => 50 ohm

the value of resistance be added to get the 2A Current is

50-20=30ohm
