Lesson 11

Which of the following equations represents Ohm's Law?

Explain how Ohm's Law can be used to determine the current flowing through a resistor when the voltage across it and its resistance are known.

• By dividing the voltage by the resistance

• By multiplying the voltage by the resistance

• By adding the voltage and resistance

• By subtracting the resistance from the voltage

Describe the process of measuring resistance using a multimeter.

• Connect the multimeter in series with the circuit and measure the current.

• Connect the multimeter across the component and select the resistance measurement mode.

• Connect the multimeter in parallel with the circuit and measure the voltage.

• Connect the multimeter to a power source and measure the power.

What is the purpose of the current division rule in circuit analysis?

• To calculate the total resistance in a series circuit

• To determine the voltage across each resistor in a parallel circuit

• To find the current through each branch of a parallel circuit

• To measure the total current in a series circuit
