Question

a bulb has. resistance of 240 Omega is connected to 12 V battery the power consumed ​

Answer 1

the power consumed by the bulb is 0.6 watt

given, resistance of the bulb, R = 240 Ω

bulb is connected to 12 volts battery. so EMF of battery, V = 12 volts.

we have to find the power consumed by the bulb due to connection in battery.

power consumption, P = V²/R

= (12)²/240

= 144/240 = 6/10

= 0.6 watt
