Series & Parallel Circuits

Question 1

Formula for total resistance in series?

Answer 1

R_total = R1 + R2 + R3 + …

Question 2

What is current in a series circuit?

Answer 2

Constant.

Question 3

Formula for total voltage in series?

Answer 3

V_total = V1 + V2 + V3 + ….

Question 4

What happens to resistance when more resistors are added in series?

Answer 4

Resistance increases → current decreases.
