Question

a heating appliances has a resistance of 115ohm if 2A current flows through it, what is the power of the appliences ​

Answer 1

Given:-

• Resistance of appliances ,R = 115Ω
• Current flow through it,I = 2A

To Find:-

• Power of Appliances ,P

Solution:-

According to the Question

It is given that a heating appliances has a resistance of 115ohm if 2A current flows through it.

We have to calculate the power of the appliances.

We know the relationship between Power ,Resistance & Current.

• P = I²R

where,

• P denote Power
• I denote Current
• R denote Resistance

Putting the value we get

→ P = 2²×115

→ P = 4 × 115

→ P = 460 Watt

• Hence, the power of the heating appliances is 460 watts.

Answer 2

Answer:

Given :-

• A heating appliances has a resistance of 115 ohm.
• The current flows through it is 2A.

To Find :-

• What is the power of the appliances.

Formula Used :-

$\clubsuit$ Power Formula :

$\mapsto \sf\boxed{\bold{\pink{P =\: I^2R}}}$

where,

• I = Current in amperes
• R = Resistance in ohms
• P = Power in Watts

Solution :-

Given :

$\bigstar\: \bf{Resistance =\: 115\: ohm}$

$\bigstar\: \bf{Current =\: 2\: Ampere}$

According to the question by using the formula we get,

$\longrightarrow \sf Power_{(Appliances)} =\: (2)^2 \times 115$

$\longrightarrow \sf Power_{(Appliances)} =\: 2 \times 2 \times 115$

$\longrightarrow \sf Power_{(Appliances)} =\: 2 \times 230$

$\longrightarrow \sf Power_{(Appliances)} =\: 460$

$\longrightarrow \sf\bold{\red{Power_{(Appliances)} =\: 460\: Watts}}$

$\therefore$ The power of the appliances is 460 Watts.
