Question

It takes 32 minutes to full charge a cell phone calculate the heat produced when 25A of current with 280 ohms resistance​

Answer 1

Answer:

3.36X10^8 J

Explanation:

Given:

t=32min=32x60s

I=25A

Resistance=280Ω

Formula:

          H=I²Rt

Solution:

          H=[25]²[280][32x60]

          H=3.36x10^8 J
