Electrical Measurement Quiz

What are the three basic units of electrical measurement mentioned in the text?

• Voltage, Current, and Power

• Voltage, Resistance, and Power

• Volts, Amps, and Ohms

• Current, Frequency, and Resistance

According to Ohm's Law, how is the current (I) calculated if the voltage (V) and resistance (R) are known?

• I = V + R

• I = V / R

• I = R / V

• I = V x R

What happens to the amperage in a circuit if the circuit resistance increases?

• The amperage increases

• The amperage remains the same

• The amperage decreases

• The amperage fluctuates unpredictably

What does Kirchhoff's Law state about the voltage drops in a series circuit?

• The voltage drops are always equal to the source voltage

• The voltage drops are always less than the source voltage

• The voltage drops are always more than the source voltage

• The voltage drops are unrelated to the source voltage

What results in an open circuit with no current flow?

• A component with a ground connection

• A component with high resistance

• A component with low resistance

• A component with no ground connection

Which of the following is NOT a type of short circuit mentioned in the text?

• Short to ground

• Short to power

• Short to resistance

• Unintended high resistance

How are loads and devices connected in a series circuit?

• In parallel

• One after the other

• In a closed loop

• Randomly

What can result from excessively high current flow through circuits?

• The circuit becomes more efficient

• The insulation melts and a fire can result

• The circuit breaks down completely

• The current is automatically redirected

How are traditional fuses, fuse links, and circuit breakers connected in a circuit?

• In parallel

• In series

• In a closed loop

• In an open circuit

What is the purpose of circuit protection devices?

• To increase the current flow
