1 Direct Current Circuits Direct Current (DC) and circuits: Direct Current: the DIRECTION of the current in a circuit does not change with time. The amplitude of the current may or may not change with time. The opposite, the Alternating Current (AC): the DIRECTION of the current in a circuit changes with time. The amplitude of the current usually changes with time as well, but may also stay constant. Battery operated circuits have usually DC.

Basic components Basic components and their symbols: Wire: connects other components in the circuit, without any resistance. Symbol: Switch: when it is closed, a circuit (a loop for the current) is formed. Symbol: Resistor: the component that follows the Ohm’s Law . Symbol: Capacitor: the component that is defined through . Symbol: Battery: the device that provides the electric potential difference in a circuit, that converts other type of energy into electric. Symbol: Inductor: will be discussed later part of this semester. Transistor: not in the scope of this course.
