Question
An electric heater draws 12 amps from a 120 volt power source. How much power does the heater dissipate?
Solution
The power P in an electrical circuit is given by the product of the voltage V and the current I. This relationship is expressed by the formula:
P = V * I
where: P is the power in watts, V is the voltage in volts, and I is the current in amperes.
Given that the heater draws a current of 12 amps from a 120 volt power source, we can substitute these values into the formula to find the power dissipated by the heater:
P = 120 volts * 12 amps = 1440 watts.
So, the heater dissipates 1440 watts of power.
