Question

An electric bulb has a power of 500w . express it in cgs system

Answer 1

Amount : 500 watts (W of power)
Equals : 5 000 000 000.00 centimeters gram/second (CGS - g cm/s / power)

Answer 2

Answer:

500 watts = 5 × 10^9 erg/s

Explanation:

Power of an electric bulb, P = 500 W

CGS system means centimeter, gram and second.

Watt is a SI unit of power.

$watt=\dfrac{Joule}{time}$

$watt=\dfrac{N-m}{s}$

$watt=\dfrac{Kg\ m/s^2\ m}{s}$ .........(1)

Also, $1\ watt=10^7\ erg/s$

So, equation (1) becomes :

$500\ watt=\dfrac{1000\ g\times 100\ cm\times\ 100\ cm}{s^3}$

$500\ watt=500\times 10^7\ erg/s$

$500\ watt=5\times 10^9\ erg/s$

Hence, this is the required solution.
