Question

You have the same two resistors on a 10 volt series circuit . Will the voltage going into the second resistor be more, less,or the same as that going into the first resistor?

Answer 1

same voltage

Step-by-step explanation:

Both the resistors will have the same voltage across it and it will be equal to 5 volt.

Now we know if the resistance value is different, then the voltage drop will be different. across them. And the current will be same in both the resistance.

Let suppose, the resistance is 5 ohm on of each one.

Therefore, total current = total voltage / total resistance

= 10 /(5+5) = 10/10 = 1 amp

So now the voltage across the 5 Ohm resistance will be = current × resistance = 1× 5 = 5 volt
