Answer :-
- Current of Device = 2.5 Ampere .
Explanation :-
As per the provided information in the given question, we have been given that the Potential Difference is 30 Volt . The Resistance is given as 12 Ohm . And, we have been asked to calculate the Current of the Device.
For calculating the Current , we will use the Formula :-
[tex] \bigstar \: \: \: \boxed { \sf{ \: Current \: = \: \dfrac{Potential \: Difference}{Resistance} \: }} [/tex]
Therefore , by Substituting the given values in the above Formula :-
[tex] \dag \: \: \: \sf { Current \: = \: \dfrac{Potential \: Difference}{Resistance} } [/tex]
[tex] \longmapsto \: \: \: \sf { Current \: = \: \dfrac{30}{12} } [/tex]
[tex] \longmapsto \: \: \: \textbf {\textsf {Current \: = \: 2.5 }} [/tex]
Hence :-
[tex]\underline {\rule {180pt} {4pt}} [/tex]
