BEEE- UNIT-I Electrical Circuits

What is Ohm's Law?

• Ohm's Law is V = I * R, where V is the voltage, I is the current, and R is the resistance.

• Ohm's Law is a mathematical equation used in biology

• Ohm's Law is a cooking technique involving baking

• Ohm's Law is a type of dance move

In a series circuit, how does the current flow through the components?

• The current flows sequentially through each component in a series circuit.

• The current flows simultaneously through each component in a series circuit.

• The current flows in reverse order through each component in a series circuit.

• The current flows randomly through each component in a series circuit.

What happens to the total resistance in a parallel circuit as more resistors are added?

• Total resistance increases

• Total resistance decreases

• Total resistance remains the same

• Total resistance becomes negative

What does the symbol 'V' represent in electricity symbols?

• Voltage

• Velocity

• Viscosity

• Volume

What is the function of a resistor in an electrical circuit?

• Resistors are only used in AC circuits

• Resistors are used to store electrical energy

• The function of a resistor is to increase voltage

• The function of a resistor in an electrical circuit is to limit the flow of current.

State the formula for calculating resistance using Ohm's Law.

• R = V x I

• R = V - I

• R = V / I

• R = I / V

How are voltage and current related in a series circuit?

• Voltage and current are directly proportional in a series circuit.

• Voltage and current are unrelated in a series circuit.

• Voltage has no effect on current in a series circuit.

• Voltage and current are inversely proportional in a series circuit.

In a parallel circuit, how does the voltage across each branch compare to the total voltage?

• The voltage across each branch is half of the total voltage.

• The voltage across each branch is equal to the total voltage.

• The voltage across each branch is greater than the total voltage.

• The voltage across each branch is unrelated to the total voltage.
