Circuits

• A circuit is a closed loop of wires and components that allows electricity to flow from one point to another
• Series circuits have one pathway for electrons to flow.
• A parallel circuit has many pathways for electrons to flow.
• In a parallel circuit, components are not dependent on eachother.
• Components in a series circuit are all connected
• An electric current is the amount of charge (number of electrons) that passes a point in the circuit each second
• The unit to measure current is Ampere, Amps for short
• The current in a series circuit is the same across all points of the circuit
• In a parallel circuit the current is not the same across all points
• Resistance limits the ability of the electrons movement
• Voltage is a measure of the amount of energy given to electrons by the power source
• Voltage = Current x Resistance
• Current = Voltage divided by resistance
• Resistance = Voltage divided by current
• Total resistance in a series circuit is the sum of all individual resistors
• Voltage in series circuit splits
• Voltage in parallel circuit is the same across all branches
• As more components are added to a series circuit, globes will become duller
• In parallel circuits when an extra component is added, current increases and resistance decreases
• In series circuits, when an extra component is added current decreases and resistance increases
• A conductor is a material that allows electric current to flow thorugh it easily because the electrons are loosely held from the nucleus
• An insulator is a material that does not allow electricity to pass through it as the electrons are tightly bound to the nucleus
• Adding a light bulb in parallel will not affect the brightness of light bulbs already in the parallel circuit.
