Series-and-Parallel-Circuits

What is Ohm's Law?

• Ohm's Law states that R = V / I.

• Ohm's Law is V = I * R.

• Ohm's Law is I = V + R.

• Ohm's Law defines power as P = I * R.

How do you calculate resistance using Ohm's Law?

• R = V / I

• R = I / V

• R = V * I

• R = V + I

In a series circuit, how does the current behave?

• The current increases at each component.

• The current decreases as it moves through the circuit.

• The current is zero at the end of the circuit.

• The current remains constant throughout the circuit.

What happens to the total voltage in a series circuit when more resistors are added?

• The total voltage increases with each added resistor.

• The total voltage remains the same; it is the sum of the voltage drops across each resistor.

• The total voltage decreases to zero with more resistors.

• The total voltage is divided equally among all resistors.

How does voltage behave in a parallel circuit?

• Voltage varies across components in a parallel circuit.

• Voltage is halved across each component in a parallel circuit.

• Voltage remains constant across all components in a parallel circuit.

• Voltage is only present at the power source in a parallel circuit.

What is the total current in a parallel circuit with two branches, one with 2A and the other with 3A?

• 5A

• 3A

• 6A

• 4A

What is the main characteristic of current in a series circuit?

• The current varies at different points in a series circuit.

• The current is zero at some points in a series circuit.

• The current is higher at the beginning of the circuit.

• The current is the same at all points in a series circuit.

How does the voltage across each resistor in a series circuit compare?

• The total voltage is divided equally among all resistors regardless of their resistance.

• The voltage across each resistor is the same in a series circuit.

• The voltage across each resistor in a series circuit is proportional to its resistance.

• The voltage across each resistor is independent of its resistance.

In a parallel circuit, if one branch fails, what happens to the other branches?

• The other branches stop working completely.

• The other branches remain operational.

• Only the failed branch continues to operate.

• All branches experience a power surge.

What is the relationship between voltage and current in a parallel circuit?

• Voltage is the same across all components, while current varies.

• Both voltage and current are the same across all components.

• Current is the same across all components, while voltage varies.

• Voltage is different across all components, while current remains constant.
