Question

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?

Answer 1

• Voltage=V=240V
• Resistance=R=12ohm
• Current be I

Apply ohms law

• V=IR
• 240=12I
• I=240/12
• I=20A

Answer 2

Answer :-

• Current is 20 Ampere .

Explanation :-

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 :-

`\bigstar \: \: \: \boxed{ \sf{ \: Current \: = \: (Voltage)/(Resistance) \: }} \\`

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

`\Longrightarrow \: \: \: \sf { Current \: = \: (Voltage)/(Resistance) } \\`

`\Longrightarrow \: \: \: \sf { Current \: = \: ( \: 240 \: )/(12) } \\`

`\Longrightarrow \: \: \textbf {\textsf { Current \: = \: 20 }} \\`

Hence :-

• Current = 20 Ampere .

Additional Information :-

`\Longrightarrow \: \: \: \sf {Voltage \: = \: Current \: * \: Resistance}`

`\Longrightarrow \: \: \: \sf {Current \: = \: \frac {Voltage}{Resistance} }`

`\Longrightarrow \: \: \: \sf {Resistance \: = \: \frac {Voltage}{Current} }`
