Circuit Analysis and Ohm's Law Quiz

What are the three key components of every electrical circuit?

• Voltage, Resistance, and Current

• Power, Energy, and Voltage

• Current, Power, and Energy

• Resistance, Power, and Energy

In a series circuit, what is true about the current through each resistor?

• It is zero through each resistor

• It is the same through each resistor

• It is half of the total current

• It varies depending on the resistor

How do you find the equivalent resistance of resistors in parallel?

• Multiply their resistances

• Subtract the smallest resistance from the largest

• Add their resistances together

• Use a method that results in a resistance smaller than any individual resistor

What is the equivalent resistance of a 15 Ohm and a 2 Ohm resistor in series?

• 17 Ohms

• 13 Ohms

• 30 Ohms

• 7.5 Ohms

If a circuit has a 20-volt battery and an equivalent resistance of 15.38 Ohms, what is the current?

• 1.50 Amperes

• 2.00 Amperes

• 0.75 Amperes

• 1.30 Amperes

What is the voltage drop across a 10 Ohm resistor with a current of 1.30 Amperes?

• 1.30 Volts

• 10 Volts

• 13 Volts

• 20 Volts

What tool is used to measure voltage in a circuit?

• Multimeter

• Ohmmeter

• Voltmeter

• Ammeter

Why should an ammeter not be connected in parallel with a resistor?

• It will cause nearly all the current to run through the ammeter, possibly damaging it

• It will increase the resistance of the circuit

• It will decrease the voltage of the circuit

• It will stop the current flow completely
