Question

1. A 2.5 V battery is connected across a resistor of 500. If the battery voltage is changed to 5 V, what should be the resistance of a resistor which will draw the same amount of current?

WITH DETAILED EXPLANITION !!!!!

Answer 1

Answer:r=v/I

I=2.5/500

Since I is same , so

2.5/500=5/r

R=1000

Explanation:

Answer 2

First lets find the current for the first situation:

I = V ÷ R

= 2.5 ÷ 500

= 0.005 A

So since current won't change therefore:

R = V ÷ I

= 5 ÷ 0.005

= 1000 Ω
