Electrical Circuits Review
It is now time to review some of the major concepts and solidify your understanding.
Answer the following questions using the resources associated with Electrical Circuits.
1... What is a short circuit? What exactly is taking place when a short circuit occurs?
2... What is the difference between a series circuit and a parallel circuit? How is voltage shared or not shared in each type?
3... Where does the term "breadboard" come from? How are they connected underneath the plastic, do you know which rows and columns are connected?
4... Draw the circuit symbol for the following: battery, LED, resistor, slide switch, push switch, motor, variable resistor, light dependent resistor and buzzer.
5... Ensure that you can build all of the following circuits.
6... Define the terms current, voltage and resistance.
7... A circuit has a current of 6 amps and a resistance of 3 ohms, what is the voltage of this circuit?
8... A circuit has a voltage of 12 V and a resistance of 4 ohms, what is the current of this circuit?
9... A circuit has a voltage of 36 V and a current of 12 amps, what is the resistance of this circuit?
10... Determine the resistance value of the following resistors.
11... A 7 segment LED has been powered in and the user wants to display the number 3. Which pins need to be powered?
12... A 7 segment LED has been powered in and the user wants to display the number 4. Which pins need to be powered?
