This question is not usually answered in conventional teachings of logic circuits. Transistors are used to build logic gates. Transistors can be easily used to represent 'high' or 'low' voltage and hence are...

we can use the subtraction method to find this out: create a table set out like this 2 7 | 2 6 | 2 5 | 2 4 | 2 3 | 2 2 | 2 1 | 2 0 128 | 64 | 32 | 16 | 8 | 4 | 2 | 1 | | | | | | | Now we simply take away eac...

Because as the voltage and current pass into the cable there is some thermal energy that is generated and for that reason the cable expands.

KCL is Kirchoff Current Law, this law says the total current walk pass a node is always zero, it is just like a water supply system, if the whole apartment is considered as a node, the water that flow outsid...

It states the relationship between the voltage or potential difference and the current passing through a material with electrical resistance. This relationship is linear and is stated as V=I*R, Where V is th...
