Question

an electric bulb is connected to 220V current is 0.50A whT is the power ofbulb​

Answer 1

$\bold {\huge {Answer :-}}$

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯

✦Given

➛Potential Difference (V) = 220 V

➛Current passing through the bulb (I) = 0.50 A

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯

✦To find

➛Power of the bulb (P)

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯

Since we know that,

$\Large\bold{\boxed{\boxed{P = V. I}}}$

$\normalsize\bold{\texttt{Putting the values in the formula}}$

$\bold{\Rightarrow P = 220 \times 0.50 }$

$\bold{\Rightarrow \: P = 110 \:watts}$

$\bold{\therefore\:Power \:of\: the\: bulb\:is \:120 \:watts\: or\: Joules/sec}$

DEFINATION→

POWER ⇨ Power is defined as the rate of consumption of energy or simply the rate of doing work.

POTENTIAL DIFFERENCE→The potential difference between two points in an electric circuit is defined as the amount of work done in moving a unit charge from one point to the other point.

Answer 2

Given

➛Potential Difference (V) = 220 V

➛Current passing through the bulb (I) = 0.50 A

✦To find

➛Power of the bulb (P)

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯

Since we know that,

P = V. I

Putting the values in the formula

P = 220 × 0.50

P = 110 Watts
