Answer:
D.3
Explanation:
Three resistors are found in the diagram. Resistors are represented by a zig-zag line, and they could be light bulbs or a hair dryer.
There are 2 resistors in the circuit. This implies the correct answer is B.
Resistors are components that are commonly used in a circuit. A resistor can be defined as an electrical component that is used in regulating the flow of electrical current in an electronic circuit.
Resistors can as well be used to provide voltage for transistors. High power resistors are used in the power distribution system and parts of motor control.
Resistors are common components of an electronic circuit and they form an integral part of electronic equipment.
The carbon composition resistors are the most common type of resistor in an electronic device, other types of resistors include
The fixed resistors are also of different types, and these include
Some Other Types of resistor include

Answer: The mass of the atom is basically the average atomic mass of all the stable isotopes.
Explanation:
Average atomic mass is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Formula used to calculate average atomic mass follows:
For Example: Taking the element silicon
Three isotopes of Silicon, which are Si-28, Si-29 and Si-30.
Average atomic mass of silicon = 28.086 amu
As, the average atomic mass of silicon is closer to the mass of Si-28 isotope. This means that the relative abundance of this isotope is the highest as compared to the other two isotopes.
Percentage abundance of Si-28 isotope = 92.2%
Percentage abundance of Si-29 isotope = 4.7 %
Percentage abundance of Si-30 isotope = 3.1%
Hence, the mass of the atom is basically the average atomic mass of all the stable isotopes.
