What else can I help you with?
What constitutes a complete circuit?
Where the current can flow around completely, without being interrupted by a break in the circuit.
What constitutes a complete electrical circuit?
A complete electrical circuit occurs when it is possible for electrical current to flow through the electrical devices in it.
What is a closed circuit?
A closed circuit is a kind of electric circuit in which the path that the electrons follow forms a complete circuit.
What causes circuit breakers to trip?
Circuit breakers trip when there is an overload of electrical current flowing through the circuit, which can happen due to too many devices being plugged in, a short circuit, or a ground fault.
What will happen to the circuit if the bulb if removed from its holder?
If the bulb is removed from its holder, the circuit will be open, breaking the flow of electricity. This will result in the current being unable to pass through the circuit and the bulb will not light up as a result.
What is a open switch circuit?
An open switch circuit is a circuit where the switch is in the "off" position or where the circuit is not complete, preventing the flow of electricity through the circuit. This results in no current flowing and no electrical devices being powered or functioning.
What do you mean by open and closed electric circuit?
An open circuit is one where the current is not able to complete the circuit. An example could be a light bulb connected to power but switched off, the circuit being broken by the switch, and considered "open." When flipping the switch On, it connects the power and the circuit is then closed.
If you cut the string with a pair of scissors what happen to the pen?
If you cut the string with a pair of scissors, the pen will likely fall or drop to the ground if it was being held up or suspended by the string. Without the support of the string, the pen loses its stability and will be affected by gravity. Depending on the height from which it falls, it may land safely or potentially get damaged.
Why doesn't the bulb light when one wire was loosen?
B/c electricity relies on there being a complete circuit for things to work. Break the circuit/loop, and the flow of electricity stops, and the light goes out.
When can a 3rd string quarterback play in a game?
When the 1st string and 2nd string quarterbacks are injured or being rested.
Can a graph have a euler circuit but not a hamiltonian circuit?
Yes. Example: .................................................... ...A * ........................................... ......|.\ ......................................... eg Euler circuit: ACDCBA ......|...\ ........... --------- ............. ......|.....\........./...............\............ The Hamilton circuit is impossible as it has two ......|.......\...../...................\.......... halves (ACD & CD) connected to each other only ......|.........\./.......................\........ at vertex C. Once vertex C has been reached in ......|.......C *........................* D.... one half, it can only be used to start a path in ......|........./.\......................./......... the other half, or complete the cycle in the ......|......./.....\.................../........... current half; or if the path starts at C, it will end ......|...../.........\.............../............. without the other half being visited before C is ......|.../ ........... --------- .............. revisited. ......|./ ........................................... ...B *.............................................. ......................................................
Write a program to copy the value of one string variable to another variable?
You can have two String variables (note that String variables are object references) refer to the same String object like so: String str1 = "Hello"; String str2 = str1; Now the str1 and str2 are references for the same String object containing the word "Hello". If you actually want a new String object with a copy of the contents of the original String, you use the String constructor that takes a String argument, like so: String str3 = new String(str1); Now str1 and str3 refer to SEPARATE String objects that happen to contain the same sequence of characters (the word "Hello"). Since Strings objects in Java are immutable, they can be shared without worrying about the contents used by one variable being upset by the use through another variable as might happen with char[] arrays in C or C++ so the first method is probably sufficient for most cases.
