Series and Parallel Circuits

What is Ohm's Law?

• Ohm's Law states that the current (I) is inversely proportional to the voltage (V) across two points.

• Ohm's Law states that the current (I) through a conductor is directly proportional to the voltage (V) and inversely proportional to the resistance (R).

• Ohm's Law states that the voltage (V) is equal to the resistance (R) divided by the current (I).

• Ohm's Law states that the resistance (R) is equal to the current (I) multiplied by the voltage (V).

What is the unit of Current?

• Volt (V)

• Ohm (Ω)

• Ampere (A)

• Watt (W)

How does current behave in a Series Circuit?

• The current is different in each component.

• The current is the same through all components.

• The current only flows through the first component.

• The current is zero in a series circuit.

What is the effect of adding more branches in a Parallel Circuit?

• It increases the total resistance and decreases the current flow.

• It has no effect on the total resistance or current flow.

• It decreases the total resistance and allows more current to flow through the circuit.

• It increases the voltage across each branch of the circuit.

What happens to the total resistance in a Parallel Circuit when more resistors are added?

• The total resistance increases.

• The total resistance decreases.

• The total resistance remains the same.

• The total resistance becomes infinite.

What is Voltage?

• The measure of electrical resistance in a circuit.

• The electrical potential difference between two points in a circuit.

• The amount of current flowing through a circuit.

• The total energy consumed by a circuit.

How does current behave in a Parallel Circuit?

• The total current is divided among the different branches, with each branch having the same current.

• The total current flows through only one branch, while the others are bypassed.

• The total current is constant and does not change across the branches.

• The total current is divided among the different branches, with each branch having a different current depending on the resistance.

What is Resistance?

• A measure of how much a component opposes the flow of current, measured in Ohms (Ω)

• A type of electrical charge

• The speed at which current flows through a conductor

• The total energy consumed by an electrical device

What happens to the total resistance in a Series Circuit when more resistors are added?

• The total resistance decreases as more resistors are added.

• The total resistance remains the same regardless of the number of resistors.

• The total resistance increases as more resistors are added.

• The total resistance fluctuates randomly with the addition of resistors.

What is the main advantage of a Parallel Circuit?

• If one component fails, the others continue to work.

• It requires less wiring than a series circuit.

• It is cheaper to build than a series circuit.

• It allows for higher voltage across components.
