Back

series

Front

What is the total resistance in a series circuit with three resistors of equal value R?

Back

R_total = R + R + R = 3R

Front

What happens to the total current in a series circuit if one component fails?

Back

The total current stops flowing.

Front

In a parallel circuit, how does the voltage across each component compare?

Back

The voltage across each component is the same.

Front

What is the formula for calculating total resistance in a parallel circuit with two resistors R1 and R2?

Back

1/R_total = 1/R1 + 1/R2

Front

How does the total current in a parallel circuit relate to the individual branch currents?

Back

The total current is the sum of the individual branch currents.
