Result
Output voltage8.25 V
Current3.75 mA
Step-by-step solution
Divider rule
Vout = Vin·R2/(R1 + R2) = 12·2200/3200 = 8.25 V
Current through the divider
I = 12/3200 = 3.75 mA
Key formulas
- Resistors in series
- Req = R1 + R2 + …
- Ohm's law
- V = I·R
Practise Series & parallel resistors
A calculator gives the answer. In the exam you need the method: practise it with new problems, hints and worked solutions.
