1. If R1 is 250K and R2 is 500K what is the voltage at A.

   
   
2. If R1 is 600K and R2 is 300K what is the voltage at A.
   
3. If R1 is 50R and R2 is 250R what is the voltage at A.
   
4. If R1 is 100R and R2 is 300K what is the voltage at A. (Be careful ! convert 300K into ohms first)
   
5. If R1 is 10K and R2 is 80K what is the voltage at A.
