How are resistors labeled

WebBecause surface mount resistors are so small, there is not enough space for colour code bands. The markings used to give the value of the resistor consist of 3 or 4 letters or numbers that may be easier to read with a magnifying glass. Reading the codes is made more complicated because there are number of different codes in use. WebIn the circuit shown in the figure, four identical resistors labeled A to D are connected to a battery as shown. S1 and S2 are switches. Which of the following actions would result in the GREATEST amount of current through resistor A? A) closing S2 only B) leaving both switches open as shown. C) closing S1 only D) closing both switches
