Question

how much voltage should be applied to a 50 ohm resistance to produce 1000j of heat in lose​

Answer 1

Given:

• Resistance (R) = 50 ohm
• Heat produced (H) = 1000 J
• Time (t) = 10 sec

To find:

Voltage

_______________________________

Solution:

We know that,

Substitute the values, we get

H = v²t/R

→ 1000 = (v² × 10)/50

→ 1000 = v²/5

→ 1000 = v²/5

→ v² = 5000

→ v = √5000 = 70.7 volt (approx)
