What does Ohm's Law state?

• Current is independent of voltage.

• Resistance is the product of current and voltage.

• Voltage is inversely proportional to current and directly proportional to resistance.

• Current is directly proportional to voltage and inversely proportional to resistance.

What is the formula for voltage?

• Voltage = Current x Resistance

• Voltage = Energy / resistance

• Voltage = Charge / Energy

• Voltage = Resistance / Current

What is a short circuit?

• A circuit with no current flow.

• A low resistance connection between two conductors.

• A high resistance connection between two conductors.

• A circuit with infinite resistance.

What does Kirchhoff's Current Law (KCL) state?

• Voltage drop across a resistor is always zero.

• The sum of currents entering a node is equal to the sum of currents leaving the node.

• The total voltage in a circuit is zero.

• Current is always constant in a circuit.

What is the total resistance in a series circuit?

• R_total = R1 + R2 + R3 + ...

• R_total = 1/(1/R1 + 1/R2 + 1/R3)

• R_total = R1 - R2 - R3

• R_total = R1 x R2 x R3

What does Kirchhoff's Voltage Law (KVL) state?

• The total current in a circuit is equal to the total voltage.

• To find the voltage drop across individual resistors.

In a parallel circuit, how is the total current calculated?

• I_total = I1 x I2 x I3

• I_total = 1/(1/I1 + 1/I2 + 1/I3)
