Question
An simple electric mixer uses a current of of 5 A and 2 300 J of energy in the 1 minute it is turned on for.What is the voltage required to operate this mixer?
Solution
To find the voltage required to operate the mixer, we can use the formula for power, which is P = IV, where P is power, I is current, and V is voltage.
First, we need to convert the energy used from joules to watts. Since 1 watt is equal to 1 joule per second, and there are 60 seconds in a minute, we divide 2300 joules by 60 seconds to get approximately 38.33 watts.
Then, we can rearrange the formula for power to solve for voltage: V = P/I.
Substituting the given values into the formula, we get V = 38.33 W / 5 A = approximately 7.67 volts.
So, the voltage required to operate the mixer is approximately 7.67 volts.
