Question

a cell is connected to a 4 ohm
resistance because of which heat of 10 joule is produced per second due to flowing through it obtain the potential difference applied across the resistance

Answer 1

According to joules law of heating,
H=I²×R×T
10=I²×4×1
10/4=I²
Ohm 's V=IR. sq both sides
V²=I²R²
V²=10/4. ×16
V²=40
V=2√10 volt

Answer 2

Answer:

The potential difference is 20 V.
