Electrisity

• Current = Charge / Time
• potential difference (V) is measured in volts, V
• The current is the rate at which charge flows through an object.
• Charge is measured in coulombs (C)
• Electric current is the rate at which charge flows through an object.
• Resistance (R) is measured in ohms, Ω
• Power (P) is measured in watts, W
• Time is measured in seconds, s
• A circuit diagram shows how components are connected together using symbols.
• Voltage (V) is measured in volts, V
• Current (I) is measured in amperes, A
• Power = Current x Voltage
• Potential difference is the difference between one point of a circuit to another.
• Resistance is a measure of how the components resists the flow of charge.
• The equation for electric charge is $Q=$$IT$
• The equation for potential difference is $V=$$IR$
• When resister is higher, its harder for charge to flow and lowers the current.
• When the potential difference is higher, there is a greater flow of charge and a bigger current.
