Because thereâs nothing wrong with doing it as a hobby. Itâs also going to take you a long time to get to full-time status. It took me just shy of 3 years to get to the point where we completely replaced our household income with our photography income, and that was considered fast.
In a series circuit, the voltage across a resistor is directly proportional with its resistance (Et= I(Rint+R). That means in a series circuit the voltage across the resistor will increase when the resistance in increased, while the current will reduce. A power source has internal resistance (Rint) which will be in series with the resistor R. So even though your resistor is connected across the power supply, the internal resistance Rint is in series with it.
The NIOSH states Under dry conditions, the resistance offered by the human body may be as high as100,000 Ohms. Wet or broken skin may drop the body's resistance to1,000 Ohms, adding that high-voltage electrical energy quickly breaks down human skin, reducing the human body's resistance to 500 Ohms..
