Some nets provide circuit inputs from the “outside world”; in a schematic, these input nets are generally shown entering the left side of component and/or the overall circuit. Other nets present circuit outputs to the outside world; these nets are generally shown exiting the schematic on the right. In the sample schematic below, circuit components are shown as arbitrary shapes, nets are shown as lines, and inputs and outputs are denoted by connector symbols.

In this sort of a connection all the components would receive the same voltage, while the current would be divided amongst the components.

Circuit components are manufactured with exposed metal pins (or leads) that are used to fasten them to the PCB both mechanically (so they will not fall off) and electrically (so current can pass between them). The soldering process, which provides a strong mechanical bond and a very good electrical connection, is used to fasten components to the PCB. During soldering, component leads are inserted through the holes in the PCB, and then the component leads and the through-hole plating metal are heated to above the melting point of the solder (about 500 to 700 degrees F). Solder (a metallic compound) is then melted and allowed to flow in and around the component lead and pad. The solder quickly cools to form a strong bond between the component and the PCB. The process of associating components with reference designators, loading them into their respective holes, and then soldering them in place comprises the PCB assembly process.

The same current would flow through all the components while the voltage would differ from one component to another. For example you have lit three lamps in series to the same power source, the first one would receive more voltage than the last.

The ratio between voltage and current is known as resistance. For most metallic conductors, the relationship between voltage and current is linear.

Setting the current higher degrades the linearity of the motor and causes microstep bunching and attendant low-speed vibration.

The ground is a circuit node to which all voltages in a circuit are referenced. In a constant voltage supply circuit, one terminal from each voltage supply is typically connected to ground, or is grounded. For example, the negative terminal of a positive power supply is usually connected to ground so that any current drawn out of the positive terminal can be put back into the negative terminal via ground.

The concept of complex impedance introduces a unified representation for resistors, capacitors, and inductors, whereby a circuit’s frequency response from input to output can be determined using KVL and KCL, where each element is assigned the appropriate impedance. The key assumption to this point is that the input to the circuit must consist solely of DC and/or sinusoidal signals. Now, this analysis is be extended to include arbitrary input signals by using the mathematical techniques of Laplace transforms.
