An electric appliance is connected by wires to a 240-volt source of voltage. If the combined resistance of the appliance and wires is 12 ohms, how much current is flowing through the circuit?

As per the provided information in the given question, we have been given that the Potential Difference is 240 Volt's . Resistance is given as 12 Ohm's . And, we have been asked to calculate the Current .

For calculating the Current , we will use the Formula :-

[tex] \bigstar \: \: \: \boxed{ \sf{ \: Current \: = \: \dfrac{Voltage}{Resistance} \: }} \\ [/tex]

Therefore , by Substituting the given values in the above Formula :-

[tex] \Longrightarrow \: \: \: \sf { Current \: = \: \dfrac{Voltage}{Resistance} } \\ [/tex]

[tex] \Longrightarrow \: \: \: \sf { Current \: = \: \dfrac{ \: 240 \: }{12} } \\ [/tex]

[tex] \Longrightarrow \: \: \textbf {\textsf { Current \: = \: 20 }} \\ [/tex]

Hence :-

Current = 20 Ampere .

Additional Information :-

[tex] \Longrightarrow \: \: \: \sf {Voltage \: = \: Current \: \times \: Resistance} [/tex]

[tex] \Longrightarrow \: \: \: \sf {Current \: = \: \dfrac {Voltage}{Resistance} } [/tex]

[tex] \Longrightarrow \: \: \: \sf {Resistance \: = \: \dfrac {Voltage}{Current} } [/tex]
