Question

If the potential difference across a wire is 10 V & the current passing through the wire is 1 A, the electric power is = -----​

Answer 1

⌬ Given That :

• ➮ Potential of Wire (P.D) = 10V
• ➮ Current Passing in Wire (I) = 1A

⌬ Need To Find :

• ➣ Electric Power in Wire ?

⌬ Formula To Be Used :

• ✪ P = V × I ✪

____________________

◆ Where :

• ➟ P = Power
• ➟ V = Potential Difference
• ➟ I = Current

⚘ Putting Values In Formula :

• ➬ P = V × I
• ➬ Power = 10V × 1A
• ➬ Power = 10 Watt

✇ Therefore :

• ➻ The Electrical Power will be 10Watt!

Answer 2

Information provided with us:

• If the potential difference across a wire is 10 V
• The current passing through the wire is 1 A

What we have to calculate:

• We have to calculate and find out the electric power which was running.

Using Formula:

• $\red \bigstar \underline{ \boxed{\sf{Power \: = \:Potential \: difference \: \times \: Current }}} \red\bigstar$

Here we have,

• Potential difference is 10 V
• Current is of 1V

Performing Calculations:

• Power is typically the rate of doing a specific work. Power is measured by as the amount of work done by an object in one second.
• Power is measured in watts (SI unit)

Substituting the values in the formula,

$: \longmapsto \: \tt{Power \: = \: 10 \times 1}$

$: \longmapsto \: \red{\boxed{ \tt{Power \: = \: 10W}}}$

Hence,

• If the potential difference across a wire is 10 V & the current passing through the wire is 1 A, the electric power is of 10 W
