Question

an electric current is rated 800 Wand 300V. if it is operated on 150V then calculate the power consumed.​

Answer 1

Answer:

25 W

Explanation:

Relationship between Power, Potential difference and Resistance :-

$p = v {}^{2} \div r$

Using this equation,

r=900 ohm

Again it is given that ,

potential difference equal to 150 V

Re applying the formulae we get,

POWER = 25 WATTS or 25W
