`C prop 1/R`

We can introduce a constant, V such that,

`C =V/R`

We can find V using the given data.

When `R = 360, C = 1/3` .

Therefore, `1/3 = V/360`

`V = 120`

Therefore the equation is,

`C =120/R`

The current when `R= 30` ,

`C = 120/30`

C = 4 Amps

**The current is 4 Amps when R =30 ohms.**
