Question : An electric bulb is connected to a 220 volt generator if the current is 0.50 ampere What is power of bulb ?
Answer : Power of bulb = 55 Watt
Explanation : In this Question, It is given that Resistance , R = 220 V and Current , I = 0.50 A.
•°• According to the Formula of Power ;
Power Formula : I²R
Substitute obtained value on Formula !
= I²R
= (0.5)² × 220
= 0.25 × 220
= 55 Watt
Therefore, Required Power of bulb is 55 Watt.
