An electric circuit is a path or loop through which electric current can flow. It typically consists of a power source, conductors, and electrical components such as resistors, capacitors, and inductors.
To calculate the missing resistance or voltage in a circuit, you can use Ohm's Law, which states that voltage equals current multiplied by resistance (V=IR). If you know the values of two of these variables, you can use this formula to solve for the missing one.
In a series circuit, all components are connected in a single loop, meaning the same current flows through each component. In a parallel circuit, components are connected in separate branches, so the total current is divided between them. This means that the voltage across each component is the same in a series circuit, while the voltage across each branch is the same in a parallel circuit.
In a series circuit, the total resistance is equal to the sum of all individual resistances. This means that adding resistors in series increases the total resistance in the circuit. In a parallel circuit, the total resistance is less than the smallest individual resistance due to the multiple paths for current to flow.
Voltage is the driving force that pushes electric current through a circuit. Higher voltage means more energy is available to move the electrons, resulting in a larger current. Lower voltage means less energy, resulting in a smaller current. However, the resistance in the circuit also affects the flow of current. The higher the resistance, the lower the current, regardless of the voltage.
