Series circuits are circuits where the components are connected in a single path, meaning the current flows through each component in the same direction. Parallel circuits, on the other hand, have multiple paths for the current to flow through, with each component connected to its own branch of the circuit.
In a series circuit, the total resistance is found by simply adding up the individual resistances of each component. In a parallel circuit, the total resistance is calculated using the formula 1/Rtotal = 1/R1 + 1/R2 + ... + 1/Rn, where R1, R2, etc. are the resistances of each component.
Kirchhoff's voltage law states that the sum of the voltage drops in a closed loop must be equal to the sum of the voltage sources in the same loop. This law is applied by setting up a loop in the circuit and using the equation ∑V = 0, where ∑V is the sum of all voltage drops and voltage sources in the loop.
The direction of current flow in a circuit is determined by the direction of the voltage source. Current always flows from the positive terminal of a voltage source to the negative terminal.
A multimeter is a versatile tool used in circuit analysis to measure voltage, current, and resistance. It is essential in identifying faulty components and troubleshooting circuit problems.
