Series and Parallel Circuits

What is Ohm's Law?

• Ohm's Law relates current, voltage, and resistance in a circuit.

• Ohm's Law only applies to circuits with direct current.

• Ohm's Law states that the resistance in a circuit is directly proportional to the voltage.

• Ohm's Law is a mathematical equation used to calculate the power in a circuit.

What is the formula for calculating voltage?

• V = I/R

• V = I + R

• V = I * R

• V = IR

What is the formula for calculating current?

• I = V/R

• I = V x R

• I = V + R

• I = V - R

What is the formula for calculating resistance?

• R = P/I

• R = I/V

• R = V^2/I

• R = V/I
