Question

9. What voltage is applied to a 20 ohm fixed resistor if the current through the resistor is 1.5 amps?

Answer 1

Question :-

• What Voltage is applied to a 20 Ohm fixed Resistor, if the Current through the Resistor is 1.5 Ampere ?

Answer :-

• Voltage of the Device is 30 Volt's .

Explanation :-

As per the provided information in the given question, The Resistance is given as 20 Ohm's . Current is given as 1.5 Amperes . And, we have been asked to calculate the Voltage .

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

$\bigstar \: \: \: \boxed {\sf { \: Voltage \: = \: Current \: \times \: Resistance \: }}$

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

$\Longrightarrow \: \: \: \sf { Voltage \: = \: Current \: \times \: Resistance }$

$\Longrightarrow \: \: \: \sf { Voltage \: = \: 1.5 \: \times \: 20 }$

$\Longrightarrow \: \: \: \bf { Voltage \: = \: 30 }$

Hence :-

• Voltage of Device = 30 Volt's .

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

Additional Information :-

$\Longrightarrow \: \: \: \sf {Voltage \: = \: Current \: \times \: Resistance}$

$\Longrightarrow \: \: \: \sf {Current \: = \: \dfrac {Voltage}{Resistance}}$

$\Longrightarrow \: \: \: \sf {Resistance \: = \: \dfrac {Voltage}{Current} }$

Answer 2

Answer:

• 30 Volts

Explanation:

Given:

• Resistance = 20 ohm
• Current = 1.5 Amperes

To Find:

• Voltage

Solution:

Using formula:

• Voltage = Current × Resistance

By Substituting the required values,

⇢ Voltage = 1.5 × 20

⇢ Voltage = 30 Volts.

Hence,

• The required Voltage is 30 volts
