An electric circuit is a path or network of electrical elements that allows electricity to flow. It typically includes a power source, conductors, and loads (such as light bulbs or motors).
The two main types of electric circuits are series and parallel circuits. In a series circuit, the components are connected in a single loop, while in a parallel circuit, the components are connected in multiple branches.
Electricity flows in a circuit due to the movement of electrons. Electrons are negatively charged particles that move from the negative terminal of a power source, through the circuit, and back to the positive terminal of the power source.
AC (alternating current) circuits have electricity that flows in both directions, while DC (direct current) circuits have electricity that flows in one direction. AC circuits are commonly used for household electricity, while DC circuits are used in smaller electronic devices such as phones and laptops.
According to Ohm's law, voltage (V) is equal to the product of current (I) and resistance (R). This can be written as V = I * R. Additionally, current can be calculated by dividing the voltage (V) by the resistance (R), and resistance can be calculated by dividing the voltage (V) by the current (I).
