Circuit Analysis

What is the primary law that relates voltage, resistance, and current in an electrical circuit?

• Hooke's Law

• Kepler's Law

• Ohm's Law

• Newton's Second Law

In a series circuit, how do resistors affect the current?

• The current doubles with each resistor

• The current remains the same through each resistor

• The current is halved with each resistor

• The current varies between resistors

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

• By dividing the total voltage by the number of resistors

• By adding their resistances together

• By multiplying their resistances together

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

What happens to the equivalent resistance when resistors are added in series?

• It increases

• It remains the same

• It becomes zero

• It decreases

What tool is used to measure voltage without altering the circuit?

• Wattmeter

• Ammeter

• Voltmeter

• Ohmmeter

What characteristic should a voltmeter have to avoid altering the circuit it measures?

• Zero resistance

• Infinite resistance

• Low resistance

• High voltage

How is current measured in a circuit?

• By connecting an ammeter in parallel

• By connecting a voltmeter in series

• By measuring the voltage drop across a resistor

• By connecting an ammeter in series

What is the result of connecting an ammeter in parallel with a resistor?

• It measures the voltage accurately

• It does not affect the circuit

• It can damage the ammeter

• It increases the circuit's overall resistance

What is the purpose of circuit analysis?

• To understand how electricity works in a system by studying its components

• To decrease the resistance in a circuit

• To increase the voltage in a circuit

• To convert AC current to DC current

What does Ohm's Law allow you to calculate if you know two of the three variables (voltage, resistance, current)?

• The frequency of the current

• The remaining variable

• The power consumption

• The speed of electrons
