Every day is an experiment!<\/strong><\/span><\/p>\n<p>Have you ever reached for a doorknob on a dry winter day and felt that sudden, painful &#8220;ZAP!&#8221;? That tiny spark is actually a phenomenon called &#8220;electrical discharge,&#8221; where electricity jumps across the gap between your finger and the knob. What&#8217;s truly astonishing is that the voltage generated in that split second is far beyond what you might imagine.<\/p>\n<h3 data-pm-slice=\"1 1 []\">The Power of Static Electricity is in the Ten-Thousands of Volts!<\/h3>\n<p>If there were a mere 1cm gap between your finger and the doorknob, the voltage required for a discharge to occur is an incredible approximately 30,000 Volts! Considering that the outlets in our homes provide 100V, that&#8217;s a staggering 300 times the voltage! This clearly illustrates the immense power of static electricity.<\/p>\n<p>You might be wondering, &#8220;With such high voltage, why doesn&#8217;t it electrocute me?&#8221; The reason is that, although the voltage is high, the amount of &#8220;current&#8221; (amperage) flowing is minuscule, and it lasts for only an instant. It\u2019s like a garden hose spraying water vigorously (high voltage), but if the total amount of water is only a cup (low current), it won&#8217;t cause much harm.<\/p>\n<p>So, what if the discharge distance was around 3mm? In this case, the necessary voltage would be about 10,000 Volts. That&#8217;s still 100 times the voltage of a standard outlet! (As a side note, compared to Pikachu&#8217;s signature move, &#8220;Thunderbolt (100,000 Volts),&#8221; this is only about one-tenth of the energy. Gotta respect Pikachu!)<\/p>\n<p><span style=\"font-size: 14px;\">In this experiment, we safely generated and discharged this everyday 10,000-Volt static electricity and filmed the process.

Observing 10,000-Volt Discharge<\/h3>\n<p>Let&#8217;s try to observe the discharge you saw in the video for yourself.
