but they do affect the overall design. The first is the Vbe drop. For a normal silicon transistor, this should be about 0.6 or 0.7 volts, dependant on temperature. If the real circuit or an ...

They are often used to power small devices such as a calculator. This circuit diagram shows the same circuit, but uses circuit symbols to represent the cell, bulb and wires. To draw an accurate ...

can be connected together to form a circuit. A circuit diagram shows how the components are connected. The following symbols show the different components that can be found in an electrical circuit.
