When a potential difference of 200V is applied across a given resistor,it draws a current of 3A. If 30V is applied across the resistor, what will be the current ??

It can be find out by V/(I*R) where V = voltage, I is current and R is resistance.
According to it
R = V/I = 200/3 = 16.667 ohm
Now we have value of R therefore for 30V, current will be I = V/R = 30/16.667 = 1.799964 A
= 1.799 or 1.8 A

Since V=IR
So R=V/I=200/3 ohm
Using this value of R for second case
V=IR
30=(200/3) I
→I=90/200=0.45 amp
Hope your work is done
