Series Circuits

Q1: The total resistance of a circuit is 680 . The percentage of the total voltage appearing across a 47  resistor that makes up part of the total series resistance is

A 68%

B 47%

C 69%

D 6.91%

ANS:D - 6.91%

At 680 ohm Resistance = Voltage is 100%,
Then at 47-ohm resistance = Voltage is?
47 *100/680 = 6.9117647045 ~ 6.91%.
