circuits

• Voltage is the potential difference between two points in a circuit and is measured in volts.
• The formula for calculating resistance is R = V / A, where R is resistance, V is voltage, and A is current.
• Resistance is the opposition to current flow and is measured in ohms (Ω).
• Current is the flow of electrons through a conductor and is measured in amps (A).
• The two main types of electrical circuits are series circuits and parallel circuits.
• Resistors release thermal energy as electric current passes through them, which helps regulate power flow in circuits.
