Question 39
H

Two different fixed resistors are connected in series across a supply. Their voltage readings are 2.0 V and 4.0 V. They are then connected in parallel across the same constant supply. What is the ratio of the current in the resistor that originally had 2.0 V across it to the current in the other resistor?
