Can someone please help with this question? The answer is C. I don’t understand how voltage across R1 is twice that across R2 (statement 2) when R1 resistance is twice that of R2. I thought it would be the opposite, statement 3. Thank you.
In series current is the same across the circuit which means in this instance it acts as constant (this means that in V=Ir) as it acts as aconstant, V is proportional to R meaning statement 2 is correct

Thank you. I though current is inversely proportional to resistance? So how can statement 4 be true? Thank you.
Thats true and it is part of Ohms Law but works when voltage is constant, but that isnt the case here. In a series circuit theres only one route for current to flow, so current is constant throughout (it varies with parallel circuits though), whereas the voltage varies here and the resistance is defined
