Calculating Capacitance for a Given Energy and Voltage?

AI Thread Summary
To calculate the capacitance of a capacitor storing 0.12 J of energy at a voltage of 6 V, the relevant formula is E = 1/2 C V^2. Rearranging this formula to solve for capacitance gives C = 2E/V^2. Substituting the values, C = 2 * 0.12 J / (6 V)^2 results in a capacitance of 0.004 uF. Understanding the relationship between energy, voltage, and capacitance is essential for solving such problems effectively.

Homework Statement



A capacitor stores 0.12 J energy when connected to 6 V voltage source. What is the capacitance of this capacitor? (UNIT:uF)

I am just not sure how to go about answering this question.

The formula for capacitance is C=(Q/V), but I am not sure how to incorporate energy into that formula.

Any help would be appreciated

Thanks
