Power is the product of voltage and current.
voltage is 2.5 V
current is 7.5*10⁻³ ampere
multiplying both
We get 18.75 *10⁻³ watts
you can also wrote this as 18.75 milli watts

Power = voltage x current
P = VI
voltage =2.5 V
current = 7.5 x 10⁻³ ampere
so P = 18.75 *10⁻³ watts
P = VI
voltage =2.5 V
current = 7.5 x 10⁻³ ampere
so P = 18.75 *10⁻³ watts
