Question

2A currenr flowing through any conductor for 10 second produces 80 joule heat calcute the canductor

Answer 1

Given :-

• Heat (H) = 80 joules
• Current (I) = 2 A
• Time (t) = 10 seconds

To Find :-

• Resisiatnce (R) = ?

Answer :-

• Resisiatnce (R) = 2 Ω

Explaination :-

As we know that,

• H = I²Rt

Subsitute the given values in above given formula :

→ 80 = (2)² R (10)

→ 80 = 4 × R × 10

→ 80 = 40R

→ R = 80/40

→ R = 8/4

→ R = 2 Ω

Therefore,the resisiatnce of the conductor is 2 Ω.

Some other Formulas :

• Speed = d/t

• F = m. a

• a (bar) = v - v_0/t = Δv/Δt

• w = F x d

• P = W/Δt

• V = 1R

• PE = mgh

• p = mv

Now ,

$\large{ \boxed{\bf H \: = I²RT \:\: }}$

❥ Put the values in above given formula :

✒ 80 = (2)² R (10)

✒ 80 = 4 × R × 10

✒ 80 = 40R

✒ R = 80/40

✒ R = 8/4

✒ R = 2 Ω

$\large{ \boxed{\bf Resistance \: of \: the \: conductor \: = 2Ω \:\: }}$

❃ Extra shots

☞ What is resistance ? ⠀

❥ Resistance is defined as a refusal to give in or to something that slows down or prevents something. ⠀

⠀It's denoted by R .

It's directly proportional to applied voltage and inversely proportional to the current.⠀

☞ R ∝ V/I

or

☞ R = V/I ⠀
