Question

please answer the above question in steps​

Answer 1

Given :-

• Voltage = 24V
• Current = 3A

To Find :-

• Resistance
• Current through the resistor if the voltage changes to 12V

Solution :-

We know :-

V = IR

• V denotes voltage
• I denotes current
• R denotes resistance

$: \implies \sf R = \dfrac{V}{I}$

$: \implies \sf R = \dfrac{24}{3}$

$: \implies \sf R = 8$

Resistance = 8Ω

Current through the resistor if the voltage changes to 12V :-

$: \implies \sf I = \dfrac{V}{R}$

$: \implies \sf I = \dfrac{12}{8}$

$: \implies \underline{\bf I = 1.5A}$

Answer 2

• Voltage=V=24V
• Current=I=3A
• Resistance=R=?

Using ohms law

$\boxed{\sf R=\dfrac{V}{I}}$

$\\ \sf\longmapsto R=\dfrac{24}{3}$

$\\ \sf\longmapsto R=8\Omega$

Now

• V=12V

Finding current

$\\ \sf\longmapsto I=\dfrac{V}{R}$

$\\ \sf\longmapsto I=\dfrac{12}{8}$

$\\ \sf\longmapsto I=1.5A$
