Question

A 9V battery is connected to a resistor having the resistance of 10 12. What is the
power across the resistor?​

Answer 1

Explanation:

1. find current using V=IR
2. then use formula P=VI or i²R

Answer 2

Answer:

I = V/R

= 9/10

= 0.9 ampere

Now,

P = VI

= 9×9/10

= 18/10

= 0.18 Watt
