Question

1.5V, 3ohm resister
Calculate Power​

Answer 1

Answer:

$Power = 0.75 \: watt$

Explanation:

Given:-

• potential difference,V = 1.5 V
• resistance,R = 3 ohm

We know that,

$Power = \frac{ {(V)}^{2} }{R}$

$\: \: \: \: \: \: \: \: \: \: \: \implies \: \frac{</u></em></strong><strong><em><u>2</u></em></strong><strong><em><u>.</u></em></strong><strong><em><u>2</u></em></strong><strong><em><u>5}{3}$

$\: \: \: \: \: \: \: \: \: \: \: \implies \: \boxed{Power = </u></em></strong><strong><em><u>0</u></em></strong><strong><em><u>.</u></em></strong><strong><em><u>7</u></em></strong><strong><em><u>5</u></em></strong><strong><em><u> \: watt}$

Answer 2

Ans= 0.75 W

Explanation:

V= 1.5v

R= 3 ohm

Formulae:-

P= V²/R

P= 1.5²/3

P= 2.25/3

P= 225/3×100

P= 3/4

P= 0.75 W
