R3 is the answer
E = 240 Volts
R1 = 30 Ohms
R2 = 80 Ohms
R3 = 100 Ohms
I = E/(R1+R2+R3) = 240/210 = 1.143A
V1 = I*R1 = 1.143 * 30 = 34.3 V.
V2 = I*R2 = 1.143 * 80 = 91.4 V.
V3 = I*R3 = 1.143 * 100 = 114.3 V.
The voltage across R3 is higher than the rated voltage.
A resistor is a two-terminal passive electrical component that mounts electrical resistance as a circuit element. In electronic circuits, resistors are used, among other things, to reduce current flow, regulate signal levels, split voltages, bias active elements, and terminate transmission lines.
