Question

a bulb when cold has 1 ohm resistance. It draws a current of 0.3 ampere when glowing from a source of 3 volts .calculate the resistance of the bulb when glowing and explain the reason for the difference in resistance?

Answer 1

R=V/I
SOresistance R=3/0.3
=10 ohm
difference in ohm is due to difference in voltage

Answer 2

Answer:

Explanation:

V = 3V

I = 0.3A

Resistance (R) = V/I

So by putting values in the formula,

R= 3/0.3 = 10 ohm.

And that's your answer.
