Let's explore the meaning of EMF, terminal voltage, and internal resistance of a cell. And see the difference between these two, which is always confusing for me.

We are developing methods for analyzing a circuit. So far we've defined the most common components (resistor, capacitor, and inductor) and sources (voltage and current). Now we need a crisp …

When we're setting up a circuit, if we have a complicated circuit, we're setting it up, we have to give names to all the voltages and all the currents. And this is the way you do it to make sure that Ohm's …

Electrons flow from the negative terminal to the positive terminal. Conventional current I travels from the positive terminal (higher electric potential), through the circuit, and finally to the negative end (lower …

Thus, conventional current flows from the positive to the negative terminal, while in reality, electrons flow from the negative to the positive terminal of a cell.

Master the art of analyzing circuits with multiple batteries and resistors to find the current flowing through each component. Boost your electrical engineering skills and conquer challenging circuit questions.

@Washington I agree with everything you said and I just want to say that this project was to better my skills in

网孔电流法是也是一个完备的解电路的方法。 （还有一个是节点电流法。） 和其它的电路分析一样，我们需要解一个包含 2 E 个独立方程的方程组，其中 E 是电路元件的数量。网孔电流法能更有效地处 …

In most cases, the current flows out of the positive terminal of a voltage source. If you apply the passives sign convention to the voltage source, in most cases the current ends up with a negative sign.

Let's learn how to calculate current and voltage across each resistor in a circuit.
