Calculate the power of a hair dryer that operates on 120V and draws a current of 10 A.
power is voltage multiplied by current.
How much heat does it produces in 10mins by a hairdryer with the following specification (240V :1,8KW )
1200
?????????????pls help
To calculate the power of a hair dryer, you can use the formula:
Power (P) = Voltage (V) x Current (I)
In this case, the hair dryer operates on 120V and draws a current of 10A. Plugging these values into the formula:
P = 120V x 10A
P = 1200W
Therefore, the power of the hair dryer is 1200 Watts (W).
