A bulb runs on a current of 0.2A from a 6v supply calculate the energy produced in 3minutes
We can use the formula:
Energy = Power x Time
To find the power of the bulb, we can use the formula:
Power = Current x Voltage
So, Power = 0.2A x 6V = 1.2W
Now we can calculate the energy produced:
Energy = Power x Time = 1.2W x 3min x 60s/min = 216J
Therefore, the energy produced by the bulb in 3 minutes is 216J.
To calculate the energy produced by the bulb, we need to use the formula:
Energy (in Joules) = Power (in Watts) × Time (in seconds)
First, let's find the power used by the bulb:
Power (in Watts) = Current (in Amperes) × Voltage (in Volts)
Given that the current is 0.2A and the voltage is 6V:
Power = 0.2A × 6V = 1.2W
Now, let's convert the time of 3 minutes into seconds:
Time (in seconds) = 3 minutes × 60 seconds/minute = 180 seconds
Finally, we can calculate the energy produced by the bulb:
Energy = Power × Time = 1.2W × 180 seconds = 216 Joules
Therefore, the energy produced by the bulb in 3 minutes is 216 Joules.
