12. The long leg of an LED is called an __________________________ which connects to _​___________________​_ the shorter leg connects to _________________________.

Answer 1

Answer 2

Here are the answers to fill in the blanks:

9. The difference in energy between one point of a circuit and another is called: voltage. The symbol used to denote it is: V.

10. 
    

11. The amount of electrical charge flowing past a specific point in your circuit is called: current. The measurement we use for it is called: ampere and it uses the I symbol.

12. 
    

13. How much a component reduces the electrical flow of energy moving through it is called resistance. It is measured in ohms and uses the Ω symbol.

14. 
    

15. The long leg of an LED is called an anode which connects to positive (+); the shorter leg connects to negative (-) or cathode.

16. 
    

Key Notes:

• Voltage (V): Potential energy difference (e.g., battery terminals).

• Current (I): Charge flow rate (measured in amperes, A).

• Resistance (Ω): Opposes current (e.g., resistors).

• LED Polarity: Anode (+) must connect to higher voltage to light up.
