Question

An heating appliance has a resistance of 115 ohm. If 2 current flow through it. What is the Power of appliance

Answer 1

Answer:

460 watts

Explanation:

Given :

• Resistance of the heating appliance = 115 ohms

• Current flowing through the heating appliance = 2 amperes

To find :

• Power of the appliance

Power = potential difference × current

Using the ohms law :

V=I×R

V=2×115

V=230 volts

Power = V×I

Power = 230×2

Power = 460 watts

The power rating of the heating appliance is equal to 460 watts

Answer 2

Given:

• Resistance of appliance = 115 ohm
• Current = 2A

To find:

• Power

Solution:

Using ohms law

V = I × R

Where

• V : potential difference
• I : current
• R : resistance

V = 115 × 2

V = 230 V

Now , we know that

P = V × I

Where

• P : power
• V : already given
• I : already given

P = 230 × 2

P = 460 W

Hence , power = 460 W
