A circuit is a closed loop of electrical current. If the loop is open or doesn’t allow the current to return to its starting position, electricity will not flow through the circuit and any devices on that partial loop will not work. Common ways of breaking a circuit include switches or blown/removed light bulbs.
is a principle in physics that is used to analyze electrical circuits. It states that the sum of the voltage drops around a closed loop in a circuit must be equal to the sum of the voltage gains around the loop.
Here are some key points about :
Circuit components can be connected in either series or parallel. A series connection has 1 path between the components that all the current must travel through. A parallel circuit has 2 or more paths between the components. The current in a parallel circuit is split between all the available paths.
Here are some key points about parallel and series connections:
Kirchhoff’s Voltage Law (KVL) is used when we’re trying to analyze the current, voltage, and resistance of a circuit. The law simply states that if you have a loop in a circuit, the total across the components and voltage source must equal 0. (Oftentimes, I’ll reword this to say that the voltage drops of the components must equal the voltage of the source).
When we look at the entire circuit as a system, energy must be conserved. All of the electrical energy provided by the battery is given to the electrons (and is represented as voltage). As the electrons do work in the other components, the energy is transferred to the components and the voltage must decrease. When the electrons reach the battery again, they have completed the loop and given all their energy away.

a) With the switch open and all the capacitors acting like open switches as well ("connected for a long time"), there's no current flowing through the ammeter.
Conservation of Energy
: Conservation of energy is a fundamental principle stating that energy cannot be created or destroyed; it can only be transferred or transformed from one form to another. In other words, the total amount of energy in a closed system remains constant over time.Current Law
: Current law refers to Ohm's Law, which states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to its resistance.Electric potential energy
: Electric potential energy is the stored energy that results from the position or configuration of charged particles within an electric field.Kirchhoff's junction rule
: Kirchhoff's junction rule, also known as Kirchhoff's first law or the conservation of electric charge, states that the total current flowing into a junction in an electrical circuit is equal to the total current flowing out of the junction. In other words, electric charge is conserved at a junction point in a circuit.Kirchhoff's Loop Rule
: Kirchhoff's Loop Rule, also known as Kirchhoff's Voltage Law (KVL), states that the sum of the voltage drops around any closed loop in a circuit is equal to the sum of the voltage sources in that loop.Parallel Connection
: A parallel connection refers to a circuit configuration where multiple components are connected side by side, allowing the current to split and flow through each component independently.Voltage Drop
: Voltage drop refers to the decrease in electrical potential energy across a component or part of a circuit due to its resistance or impedance.Voltage Gain
: Voltage gain represents how much an amplifier increases an input voltage signal and is usually expressed as a ratio or in decibels (dB).4 min read•january 8, 2023
