General Physics

• Nikola Tesla is known for his invention of the tesla coil which generates high voltage sparks.
• Cellphones and chargers are examples of devices that use Tesla's invention.
• Static Electricity is the accumulation of electric charge on the surface or within a material.
• Current Electricity is the flow of electric charge and defines the way we live and is dynamic in nature.
• Electric Potential is the energy capacity of a unit charge.
• Voltage is the push or pressure, the pressure from an electrical circuit’s power source that pushes charges through a conducting loop, enabling them to do work.
• Resistance is the opposition to the flow of electrons in an electrical circuit and is the main cause of heat generation in electrical circuits.
• Current is the rate at which charges flow.
• Conventional Current behaves as if positive charge carriers cause current.
• Electron Flow is the flow of negative charge.
• Open Circuit is a switch OFF one where the continuity has been broken by an interruption in the path for electrons to flow.
• Closed Circuit is a switch ON one that is complete, with good continuity throughout.
• Short Circuit is an electric circuit offering little or no resistance to the flow of electrons.
• The longer the wire, the less current flows through it, the greater the resistance.
• Circuit is a closed loop which electrical charges can continuously flow.
• Current = 0.176 Amps
• Resistance = 1.5 Ohms
• Multimeter is a device that can be used to measure voltage, current, and resistance.
• Amperes (Amps) measures the electrical current and is how quickly electrons can flow past a specific point in the wire during a given amount of time.
