This is the current in the 470 resistor. The voltage across that resistor can be found by Ohm’s law. Thus the voltage across the parallel combination must be . This is the voltage across both the 820 and 680 resistors, since parallel resistors have the same voltage across them. Note that this voltage value could also be found as follows.

Parallel resistors have all have the same pd across them but the currents add, so: Itot = V / Rtot = V / R1 + V / R2 etc... then divide by V to get the familiar formula. Beware that the parallel formula is usually quoted as 1 / Rtot so they still have to …
