Ohm’s Law & Kirchhoff’s Laws

What is Ohm's Law?

• Ohm's Law is V = I * R, where V is voltage, I is current, and R is resistance.

• Ohm's Law is a mathematical equation used in biology.

• Ohm's Law is a type of dance move popular in the 1980s.

• Ohm's Law is a cooking technique for baking cakes.

What is the formula for Ohm's Law?

• I = R / V

• I = V / R

• I = V + R

• I = V x R

What does Kirchhoff's Current Law state?

• Total current entering a junction equals total voltage leaving the junction

• Total voltage entering a junction equals total current leaving the junction

• Total current entering a junction equals total current leaving the junction

• Total voltage entering a junction equals total voltage leaving the junction

What does Kirchhoff's Voltage Law state?

• Voltage drops are not equal to voltage rises in a circuit.

• The sum of currents around a closed loop in a circuit is zero.

• Voltage is always constant in a circuit.

• The sum of voltages around a closed loop in a circuit is zero.

How do you analyze series circuits?

• Count the number of components, Measure the temperature of the circuit, Guess the resistance values

• Calculate total resistance, total current, and voltage drops across each component.
