FREE TN LLE Electrical Theory Questions and Answers
What is Ohm's Law?
Correct!
Wrong!
Ohm's Law states that the voltage (V) across a conductor is equal to the current (I) flowing through it times its resistance (R).
In a series circuit, if you add more resistors, what happens to the total resistance?
Correct!
Wrong!
In a series circuit, the total resistance is the sum of all individual resistances, so adding more resistors increases the total resistance.
What is the primary characteristic of a parallel circuit?
Correct!
Wrong!
In a parallel circuit, all components share the same voltage, but the current can vary between different branches.
What unit is used to measure electrical power?
Correct!
Wrong!
Electrical power is measured in watts (W), which represents the rate of energy consumption or generation.
Which component is used to store electrical energy in an electric field?
Correct!
Wrong!
A capacitor stores electrical energy in an electric field and is used in various electrical applications to regulate voltage and power flow.
