What Is the Voltage Across a Resistor in a Parallel Circuit?

[soupastupid]

Homework Statement

A circuit with one 5V and 3 resistors in parallel. What is the voltage across one of the resistors?

Homework Equations

V=IR

The Attempt at a Solution

5/3 V??

or should i put
R1 = 5V/I -R2-R3 V

how do we get voltage across one of the resistors without being given current or current of each resistor?

If you have 3 resistors in parallel with a voltage source then the output of the voltage source is directly onto each of the 3 resistors.
