An electric bulb ismarked 6O watts, 24O vocts find the current required to lightthe bulb
P = EI
So plug in P and E, and solve for I
power = voltage * current ... 60 = 240 * ? ... amperes
To find the current required to light the bulb, you can use Ohm's Law, which states that current (I) is equal to power (P) divided by voltage (V). The formula is:
I = P / V
Given that the power (P) is 60 watts and the voltage (V) is 240 volts, we can substitute these values into the formula:
I = 60 watts / 240 volts
Simplifying:
I = 0.25 amperes (or 250 milliamperes)
Therefore, the current required to light the bulb is 0.25 amperes (or 250 milliamperes).
