Which current is more dangerous

Resistance in DC:. Now resistance in AC also known as impedance. If we put frequency as 50 or 60Hz, the overall impedance i. This way, AC has the ability to easily pass through the capacitor. It means AC is more dangerous than DC in case when human body act as a capacitor. In short, the impedance and resistance in DC is lower than AC as it decreases when frequency increases.

This way, AC is more harmful than DC. Some having the concept that DC is more dangerous than AC with the same level of voltage because AC changes it direction multiple times i. AC touches the zero value 50 or 60 times per second due to frequency and there is a chance for victim to skip the shock, whereas there is no frequency in DC.

Now if we consider the frequency as 60 or 50Hz, lets see how fast AC changes its direction. It shows that AC touches the zero point in after each 0. For example, low voltage about 25V AC with 60 Hz are harmful wet and humid body.

In case of electric shock, try to disconnect the power supply and push back the victim body from the source keep in mind that you should properly insulated before doing so. Only call the professional electrical in case of repairing or troubleshooting. In case of emergency , call the local authority ASAP.

For sake of electric shock dc power is more dangerous than single ac power. Ac is more dangerous than Dc. Alternating current has got peak value fifty times in a second which is higher than steady value of dc. Equivalent RMS of ac. Your email address will not be published.

People have given good answers. But here's a fun fact. The spark which you see off metal door knobs and sweaters in winter are a minimum of 10, V. I didn't die of it.

An 'old school' trick to test whether a 9V battery is empty, is to put both contacts on your tongue.

If it tingles, you know there is a current and the battery still has some juice. I did this several times to check a battery, and so far I didn't die.
