Voltage and Current in a Resistor Network

In summary, voltage is the potential difference between two points in a circuit and is required to move electrons through a resistor network. Current is the flow of electric charge and is directly proportional to voltage according to Ohm's Law. Adding resistors in series increases the total resistance and decreases the current, while adding resistors in parallel decreases the total resistance and increases the current.

when i connect a sinusoidal voltage source to resistors all voltages and currents become zeros.
another problem is how to plot the voltages and currents for any component.
if anybody has a book or link it would help please reply. thank you
check the attached picture

Looks like you haven't defined an amplitude for your source...

It is important to understand that when a sinusoidal voltage source is connected to a resistor network, the voltages and currents do not become zero. Instead, they may change in magnitude and phase. This is because resistors offer resistance to the flow of current, but they do not completely block it. Therefore, there will always be some voltage and current present in the network.

To plot the voltages and currents for any component in the network, you can use a circuit analysis tool such as SPICE or MATLAB. These tools allow you to enter the circuit components and their values, and then simulate the circuit to obtain the voltage and current values at different points. You can also use a multimeter to measure the voltage and current at specific points in the circuit.

If you are looking for a book or link to further understand voltage and current in resistor networks, I recommend checking out "Electric Circuits" by James W. Nilsson and Susan A. Riedel or "Circuit Analysis: Theory and Practice" by Allan H. Robbins and Wilhelm C. Miller. These books provide a comprehensive understanding of circuit analysis, including resistor networks and how to plot voltages and currents. Additionally, there are many online resources and tutorials available that can help you understand and visualize voltage and current in a resistor network.
 

FAQ: Voltage and Current in a Resistor Network

What is voltage in a resistor network?

Voltage, also known as electromotive force, is the potential difference between two points in a circuit. In a resistor network, voltage is the amount of energy required to move electrons through the network.

What is current in a resistor network?

Current is the flow of electric charge in a circuit. In a resistor network, current is the rate of flow of electrons through the network. It is measured in amperes (A).

How are voltage and current related in a resistor network?

According to Ohm's Law, voltage and current are directly proportional in a resistor network. This means that as voltage increases, current also increases, and as voltage decreases, current decreases. The relationship is described by the equation V = IR, where V is voltage, I is current, and R is resistance.

What is the effect of adding resistors in series in a resistor network?

When resistors are connected in series in a resistor network, the total resistance of the network increases. This means that for a given voltage, the current will decrease. The total resistance is calculated by adding the individual resistances together.

What is the effect of adding resistors in parallel in a resistor network?

When resistors are connected in parallel in a resistor network, the total resistance of the network decreases. This means that for a given voltage, the current will increase. The total resistance is calculated using the equation 1/Rt = 1/R1 + 1/R2 + 1/R3 + ..., where Rt is the total resistance and R1, R2, R3, etc. are the individual resistances.
