Kirchhoff's Voltage Law - Comprehension Quiz

What did Gustav Kirchhoff announce in 1845?

• Faraday's law

• Newton's laws

• Ohm's law

• Kirchhoff's laws

What does Kirchhoff's voltage law state?

• The sum of all the powers in a circuit equals zero

• The sum of all the voltages in a circuit equals zero

• The sum of all the currents in a circuit equals zero

• The sum of all the resistances in a circuit equals zero

What is the formula to find the equivalent (total) resistance in a series circuit?

• Req = R1 + R2 + R3 + ... + Rn

• Req = R1 * R2 * R3 * ... * Rn

• Req = R1 / R2 / R3 / ... / Rn

• Req = R1 - R2 - R3 - ... - Rn

What is the circuit current formula in a series circuit?

• Is = Vs + Req

• Is = Vs - Req

• Is = Vs * Req

• Is = Vs / Req

What is the voltage formula for each load in a series circuit? (Example: voltage in Resistor 1)

• V_R1 = Is x R1

• V_R1 = Is + R1

• V_R1 = Is - R1

• V_R1 = Is / R1
