Phase angle measurement of leakage current – capacitive coupling detection ; Some standards allow for in-phase and quadrature currents to be measured separately. Leakage current due to capacitive coupling may not be a safety concern; Min/max pass/fail current limits: Separate limits during ramp; Programmable multichannel testing
Leakage current is the small amount of electrical current that flows through an insulating material or dielectric, even when there should ideally be no current. This current can affect the performance and efficiency of electronic circuits and systems, making it crucial to monitor and minimize leakage.
Power is the product of voltage and current, so the equation is as follows: P = V × I. With this formula you can calculate, for example, the power of a light bulb. If you know that the battery voltage is 18 V and current is 6 A, you can that the wattage will be 108 W with the following calculation: P = 6A × 18V = 108 watts

C4 reduces output noise and has little effect on the leakage current, the dominant components being CY1 and CY2 between line and earth and neutral and earth. Lower capacitance values of CY1 and CY2 will result in a lower leakage current. But it may then cause the power supply to fail the conducted and radiated EMI standard requirements.
Leakage current is also any current that flows when the ideal current is zero. Such is the case in electronic assemblies when they are in standby, disabled, or "sleep" mode ( standby power ). These devices can draw one or two microamperes while in their quiescent state compared to hundreds or thousands of milliamperes while in full operation.
For example, an average automotive battery might have a capacity of about 70 amp-hours, specified at a current of 3.5 amps. This means that the amount of time this battery could continuously supply current of 3.5 amps to a load would be 20 hours (70 amp-hours / 3.5 amps).
