A circuit diagram is a visual representation of an electrical circuit, showing how components are connected and how electricity flows through the circuit.
Voltage is calculated by using Ohm's law, which states that voltage (V) is equal to the product of current (I) and resistance (R). In a circuit diagram, voltage can be calculated by measuring the potential difference between two points in the circuit.
Current is calculated by dividing the voltage (V) by the resistance (R), according to Ohm's law. In a circuit diagram, current can be calculated by measuring the flow of electrons through a specific point in the circuit.
In a circuit diagram, the letter "Y" typically represents a resistor, which is a component that limits the flow of electricity in a circuit. The resistor is represented by a zigzag line.
In a circuit diagram, the letter "Z" generally represents an impedance, which is a measure of how much a circuit resists the flow of an alternating current. The impedance is represented by a curved or squiggly line.
