Question

3amphere current flows through a electric ironwhich is decided to work 230 wolt for 10 second calculate the heat energy
​

Answer 1

Answer:

=6900 joule

Explanation:

[Joule heating effect]

H = I^2*R*t

H = I*V*T. [ R = v/i ohm law]

H = 3*230*10

= 6900 joule

Answer 2

Answer:

6.9Kilojoules is the required answer

Explanation:

Given:-

• Current ,I = 3 A
• Potential Difference ,V= 230v
• Time taken ,t = 10s

To Find:-

• Heat Energy ,H

Solution:-

According to the Question

It is given that 3 ampere current flows through a electric ironwhich is decided to work 230 wolt for 10 second. we have to calculate the heat energy . So by using Formula .

• H = VIt

where,

• H denote Heat energy
• V denote Potential Difference
• I denote Current
• t denote time taken

Substitute the value we get

→ H = 230 × 3 × 10

→ H = 230×30

→ H = 6900 J

→ H = 6900/1000 Kj

→ H = 6.9 Kj

• Hence, the heat energy is 6.9 Kilojoules.
