A given electrical circuit operating on "V" volts with "R" ohms of resistance draws 3.0 amps of current. How much current will it draw if "V" is multiplied by 5.9?
How much current will the circuit above draw if it is connected to the original "V" but the resistance is multiplied by 7.2?
please show all work.

[1] 3 * 5.9 = 17.7
[2] 3 / 7.2 = 0.416666

let us see........ we know by ohms law V=iR then (V1/V2)=(i1/i2)*(R1/R2) by using this formula you can get the answers easily....
