Figure shows a circuit containing a 12 V battery and three resistors, R1, R2 and R3.
Figure: Circuit containing a 12 V battery, a 4.0 Ω resistor in series with two further resistors connected in parallel with each other

Give the name of the arrangement in which resistors R2 and R3 are connected.
The potential difference across R2 is 4.0 V. Determine the potential difference across R1.
Calculate the current in R1. Use the equation: potential difference=current×resistance\text{potential difference} = \text{current} \times \text{resistance}potential difference=current×resistance
R2 has a resistance of 4.0 Ω. Calculate the current in R2.
Determine the current in R3.
