### Why doesn't current increases when the voltage is increased

When connecting two batteries in series the voltage is increased. For example: Connecting two 5V batteries in series will produce 10V voltage but the current will be the same. According to Ohm's Law <...

### Why the resistors needs higher Ampers if the Total current is 4 Ampers?

I have a question about the circuit as shown up. My question is if the total current is 4 Amperes, why do the resistors need a higher current? Am I missing something? If that so, what it is?

### Calculating current in a series circuit

Given the following circuit, it seems like we could use ohms law to conclude that current = voltage / resistance. With a source voltage of 3.3 and a resistance value of 220, current = 3.3 / 220 = .015 ...

### Application of Ohm's law to a single resistor and to a series circuit

For any given resistor following Ohm's law say a carbon resistor, it's resistance is independent of the value of current and voltage. However, say we had a 5 ohm resistor in a circuit with a 10V ...
