Use the following rules:
- The sum of currents that enter and exit a node (junction) is always zero. So if you have 3 wires that connect, through one flows 2A, the other 3A, then the third must deliver 5A (taking the direction into account!)
- The sum of voltages across different components should always add up. So if you have a battery of 10V with two unknown resistors, and over one of the resistors is 4V, you know the other one has the remaining 6V.
- With resistors, V=I*R must hold.
With these basic rules you should get a long way!
A boolean operator is one of those: and, or, not
true and true gives you true
<span>false and false gives you false
</span><span>false and true gives you false
</span><span>true and false gives you false
</span>true or true gives you true
true or false gives you true
false or true gives you true
false or false gives you false
not true gives you false
not false gives you true

Answer:
name1 + "," + name2 + "," + name3 // concatenation of the three values
Explanation:
Following are the description of statement
- The "+" operator is used for the concatenation purpose of the three str values.
- In the given question the name1 variable contains "Neville" ,name2 contains "Dean" and name3 contains "Seamus".
- Firstly we have given the name1 after that give the comma then we use "+" for the concatenation purpose and give the name2 again we will comma and finally, we will give the variable name3 by using "+" operator.
