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.
Resistance is a measure of how hard it is for a current to flow through a component in a circuit. Resistors are added into a circuit to reduce the amount of current flowing. The bigger the value of resistance, the lower the current. Components such as bulbs have resistance. When more bulbs are added to a series circuit, resistance increases. This causes the current to decrease. Your web browser does not have JavaScript switched on at the moment. For information on how to enable JavaScript please go to the Webwise site.
