Question

If the potential difference across a wire is 2 V & the current passing through the wire is 1 A, the electric power is = ----- * If the potential difference across a wire is 2 V & the current passing through the wire is 1 A, the electric power is = ----- * ​

Answer 1

Answer:

2 watt is the required electric power.

Explanation:

According to the Question

It is given that ,

If the potential difference across a wire is 2 V & the current passing through the wire is 1 A, the electric power is = ____

Potential Difference ,V = 2v

Current ,I = 1A

we need to calculate the electric power of the wire.

As we know the relationship between Current, Potential Difference and Power .

• P = VI

where,

P denote Electric Power

V denote Potential Difference

I denote Current

Substitute the value we get

➻ P = 2×1

➻ P = 2 W

• Hence, the electric power is 2 watt.

Answer 2

Answer:

Question :-

$\mapsto$ If the potential difference across a wire is 2 V & the current passing through the wire is 1 A, the electric power is ________ .

Given :-

$\mapsto$ The potential difference across a wire is 2 V and the current passing through the wire is 1 A.

To Find :-

$\mapsto$ What is the electric power.

Formula Used :-

$\clubsuit$ Electric Power Formula :

$\mapsto \sf\boxed{\bold{\pink{P =\: IV}}}$

where,

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

Solution :

Given :

$\bigstar\: \: \bf{Current\: (I) =\: 1 A}$

$\bigstar\: \: \bf{Potential\: Difference\: (V) =\: 2 V}$

According to the question by using the formula we get,

$\footnotesize\longrightarrow \sf\bold{\purple{Electric\: Power =\: Current \times Potential\: Difference}}$

$\longrightarrow \sf Electric\: Power =\: 1 \times 2$

$\longrightarrow \sf\bold{\red{Electric\: Power =\: 2\: Watt}}$

${\small{\bold{\underline{\therefore\: The\: electric\: power\: is\: 2\: Watt\: .}}}}$
