Answer:

300 volts

Step-by-step explanation:

now in this question we have been given our resistance which is 20 ohms and our current which is 15A

using ohm's law

V=IR

where v is voltage, I is current and r is resistance

now substitute,

V=15 x 20

V=300

I hope I helped

Question :-

  • An Electronic Device has a Resistance of 20 Ohm's and a Current of 15 Ampere . What is the Voltage across the Device ?

Answer :-

  • Voltage of the Device is 300 Volt's .


\rule {180pt}{2pt}

Given :-

  • Resistance = 20 Ohm's
  • Current = 15 Ampere

To Find :-

  • Voltage = ?

Solution :-

As per the provided information in the given question, we have been given that the Resistance of the Device is 20 Ohm's. It's Current is given as 15 Ampere . And, we have been asked to calculate the Voltage .

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


\bigstar \: \: \: \boxed {\sf { \: Voltage \: = \: Current \: * \: Resistance \: }}

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


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


\Longrightarrow \: \: \: \sf { Voltage \: = \: 15 \: * \: 20 }


\Longrightarrow \: \: \: \bf { Voltage \: = \: 300 }

Hence :-

  • Voltage of Device = 300 Volt's .


\underline {\rule {180pt}{4pt}}

Additional Information :-


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


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


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