Series Circuits - Engineering

Q1:

A series circuit consists of a 4.7 k, a 12 k, and a 2.2 k resistor. The resistor that has the most voltage drop is

A the 12 k

B the 2.2 k

C the 4.7 k

D impossible to determine from the given information

ANS:A - the 12 k

Explanation:

Simple logic is that, Consider 1 amp current and calculate vtg drop across each resistance you will find that the more value resistance has more voltage drop.

V = IR.

4.7*1 = 4.7.

12*1 = 12 .

2.2*1 = 2.2.
