- Current is the flow of charge per unit time.
- Electricity
- The voltage of the supply is the measure of energy given to the charges in a circuit.
- In series
- In parallel
- IS =I1=12
- VS= V1+V2
- RT-1=R1-1+R2-1
- VS= V1+V2
- IS =I1=12
- IS = 12+I2
- VS=V1=V2
- RT=R1+R2
- VS=V1=V2
- In parallel
- A voltage divider is a device or a circuit that uses two or more resistors or a variable resistor to provide a fraction of the available voltage from the supply.
- The symbol for power is P, it is measured in Watts (W).
- The symbol for energy is E, it is measured in Joules (J).
- A transistor can be used as a switch. When used as a switch, a transistor may conduct or not conduct.
- When it conducts, a transistor is said to be ON, when not conducting, it is OFF.
- The transistor is on, when the input voltage is greater than or equal to 0.7 V. (NPN) 2.0 for MOSFET
