determine the amount of heat generated per minute by a 120 volt lamp which takes 0.5 amperes.
thanks!
heat: power*timeInSecods= 120*.5*60sec/min
To determine the amount of heat generated per minute by a lamp, we need to use the formula:
Heat Generated (in Joules) = Power (in Watts) × Time (in seconds)
First, let's calculate the power consumed by the lamp:
Power (in Watts) = Voltage (in volts) × Current (in Amperes)
Given:
Voltage = 120 volts
Current = 0.5 Amperes
Power (in Watts) = 120 volts × 0.5 Amperes
Next, we need to convert the power from watts to joules per second. Since we want to find the heat generated per minute, we'll need to convert the time from minutes to seconds.
1 minute = 60 seconds
Finally, we can calculate the heat generated per minute:
Heat Generated (in Joules) = Power (in Watts) × Time (in seconds)
Heat Generated (in Joules) = Power (in Watts) × 60 seconds
Plug in the values to get the final answer.
