Varying the Voltage Across a Fixed Value Resistor

In my project to change the voltage of the fixed value resistor, consider the effect of changing the voltage of the fixed value resistor. I will observe what happens. Looking at the possibilities, I hope that you can understand what happens when the voltage changes. Planning ======== The voltages that may be affected at the time of change are as follows. Current thermal resistance I decided to change the voltage and measure the current.

There are also three values ​​that need to be determined - the current of each resistor. Use Ohm's Law to determine the current value of each resistor. This is simply the voltage drop across each resistor (60 volts) divided by the resistance value of each resistor (indicated in the description of the problem). Calculations are as follows. For mathematical analysis of this parallel circuit, concepts and equations are mixed. As is often the case with physics, it is dangerous to separate a concept from an equation when solving a physical problem. Here we need to consider the notion that the voltage drop across each of the three resistors is equal to the battery voltage and the sum of the currents of each resistor is equal to the total current. These understandings are essential for completing mathematical analysis

Ideal basic circuit parts such as resistors can be described mathematically from the viewpoint of voltage and current, but in the resistor tutorial, the voltage across the pure ohmic resistance is the current flowing through it Proportional. As shown below: Ohm's law. Consider the following circuit. When the switch is closed, the AC voltage V is applied to the resistor R. This voltage causes current to flow, and when the applied voltage goes up and down, the current goes up and down. Since the load is a resistor, both the current and voltage reach the maximum or peak value and drop to zero at exactly the same time. In other words, they rise and fall simultaneously, so they are called "in-phase".
