we are learning a lot about circuits in freshman physics 2 - does junior/senior E&M do circuits - or do i need to take a circuit course if i want to learn more about circuits beyond freshman physics 2? thx
AC (alternating current) circuits have a continuously changing direction of current flow, while DC (direct current) circuits have a constant direction of current flow. This results in different behaviors and applications for each type of circuit.
An inductor resists changes in the flow of current and stores energy in the form of a magnetic field. This can affect the behavior of a circuit by causing a delay in the flow of current or by smoothing out fluctuations in the current.
A capacitor stores electric charge and can release it quickly when needed. This allows it to act as a temporary power source, providing energy to the circuit when the main power source is unavailable or unable to keep up with the demand.
In a series circuit, the total resistance is equal to the sum of the individual resistances. This can be calculated by adding the resistance values of each component in the circuit. For example, if there are three resistors in series with values of 2 ohms, 4 ohms, and 6 ohms, the total resistance would be 12 ohms (2+4+6).
An open circuit is a circuit that is incomplete, meaning there is a gap in the path for the current to flow. This results in no current flow and the circuit not functioning. A closed circuit is a complete circuit, with no gaps, allowing current to flow and the circuit to function properly.
