A clothes dryer uses about 2 amps of current from a 240 volt line. How much power does it use?
P = E*I = 240 * 2
8 2
To calculate the power used by a clothes dryer, you need to multiply the current (in amperes) by the voltage (in volts). In this case, the current is 2 amps and the voltage is 240 volts.
The formula to calculate power is:
Power (in watts) = Current (in amperes) × Voltage (in volts)
Substituting the given values:
Power = 2 amps × 240 volts
Therefore, the power used by the clothes dryer is 480 watts.
