for one of the questions i have to find out the voltage across two resistors.

i have found out that

Resistor 1= 5 ohms

R2= 7 ohms

Voltage is 12V

and the current flow is 1 amp

but now i have to find out what the voltage drop across each of the resistors is . . . .

i have no idea how to do it

please please can anyone help me???

thanks oli
