Question

A battery of emf 3V sendsa current of 0.5A through a wire. Calculate the resistance of the wire and the heat produced in 10 minutes.

Answer 1

hey mate here is your answer ✌♥

v=3v

I=0.5a

so

resistance=v/I

=3/0.5

=6ohm

now t=10 min

=600sec

so

h=i²rt

=(0.5)²(6)(600)

=900J

hope it will help you ⛄

mark me brainliest ✌✌✌

Answer 2

Given :

Voltage (V) = 3 v

Current ( I ) = 0.5 A

By Ohm's Law , V = I R

==> R = V/I

==> R = 3 v / 0.5 A

==> R = 30 v / 5 A

==> R = 6 Ω

We also know that :

Power of the current = heat produced by it

P = V I t

==> P = 3 v × 0.5 A × 10 minutes

==> P = 3 v × 0.5 A × 600 s

==> P = 900 J

The resistance is 6 Ω and power is 900 J

Hope it helps :)
