Circuits

• In a parallel circuit, the total resistance is less than the smallest individual resistance.
• Voltage is the potential difference between two points in a circuit and is measured in volts.
• Current is the flow of electric charge in a circuit and is measured in amperes.
• Current is the flow of electrons through a conductor and is measured in amps.
• Ohm's law states that the voltage across a resistor is directly proportional to the current passing through it.
• The current flowing through any point in a series circuit is equal to the current flowing through all other points.
• Energy is the ability to do work and is measured in joules.
• The voltage across all components in series is equal to the potential difference supplied by the power source.
• The current through all components in series is equal to the current flowing from the power supply.
• Resistance is the opposition to the flow of electricity and is measured in ohms.
• Power is the rate at which energy is transferred or used and is measured in watts.
• In parallel circuits, the total resistance is less than the smallest individual component.
• Potential difference is the force driving an electrical current around a circuit and is measured in volts.
• Voltage remains constant throughout a parallel circuit.
• Current divides when branches join together.
