How can a microwave I took apart have a .9 microfarad capacitor rated for 2100v? The microwave is rated at 1800 watts. What am I missing?
1/2 CV*2=1.98 joules
1/2 CV*2=1.98 joules
I don't know why do you calculate capacitor energy. Do you know how a microwave power supply works?Samson4 said:How can a microwave I took apart have a .9 microfarad capacitor rated for 2100v? The microwave is rated at 1800 watts. What am I missing?

Samson4 said:I don't know the formula for such a calculation. How can it draw more power then the capacitor is able to provide? The power supply isn't charging to higher voltages than it's rated for.
Then, if you know how it works, I don't know what is bothering you...Samson4 said:A microwave power supply works by providing a high voltage ac current to a doubler circuit. It then feeds the rectified current into a magnetron. I am definitely not the one to be answer question of the sort though.
I thought it was a power capacitor; that is what was bothering me. Drakkith already helped me, but thanks anyway.zoki85 said:Then, if you know how it works, I don't know what is bothering you...
To calculate the joules from watts for a microwave capacitor, you can use the formula J = W x t, where J is the energy in joules, W is the power in watts, and t is the time in seconds. First, determine the power rating of your microwave capacitor in watts. Then, calculate the time it takes for your microwave to run by multiplying the cooking time per minute by the number of minutes you plan to cook. Finally, plug these values into the formula to calculate the joules.
Yes, you can use the wattage listed on your microwave to calculate joules. The wattage listed on a microwave is the power rating, which is measured in watts. You will need this value to calculate the joules using the formula J = W x t.
To convert watts to joules, you can use the formula J = W x t, where J is the energy in joules, W is the power in watts, and t is the time in seconds. First, determine the power rating of your microwave capacitor in watts. Then, calculate the time it takes for your microwave to run by multiplying the cooking time per minute by the number of minutes you plan to cook. Finally, plug these values into the formula to calculate the joules.
Watts and joules are both units of measurement for energy. Watts measure the rate of energy transfer, while joules measure the total amount of energy. In a microwave capacitor, the watts indicate the power rating, while the joules represent the total energy used during the cooking process. They are related by the formula J = W x t, where J is the energy in joules, W is the power in watts, and t is the time in seconds.
Calculating joules from watts for a microwave capacitor is important because it allows you to understand the total energy used during the cooking process. This information can be useful for determining the efficiency of your microwave and managing your energy consumption. It also gives you a better understanding of the power and energy requirements for different cooking tasks, helping you to use your microwave more effectively.
