What is the formula to calculate the total resistance in a series circuit?

Back

R_total = R1 + R2 + R3 + ...

Front

How do you calculate the current flowing through a circuit with a known voltage and resistance?

Back

Use Ohm's Law: I = V/R.

Front

What is the relationship between voltage, current, and resistance in a circuit?

Back

Ohm's Law: V = I * R.

Front

What happens to the total resistance in a parallel circuit as more resistors are added?

Back

The total resistance decreases.

Front

What is the unit of capacitance?

Back

Farad (F).
