Parallel Circuits

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where the components are connected across common points or junctions, providing multiple paths for current to flow.

What happens to the total current in a parallel circuit?

Back

In a parallel circuit, the total current is the sum of the currents flowing through each parallel branch.

Front

How does voltage behave in a parallel circuit?

Back

In a parallel circuit, the voltage across each component is the same and equal to the source voltage.

Front

What is the formula for calculating total resistance in a parallel circuit?

Back

The total resistance (R_total) in a parallel circuit can be calculated using the formula: 1/R_total = 1/R1 + 1/R2 + 1/R3 + ...

Front

If one branch of a parallel circuit is open, what happens to the current in the other branches?

Back

If one branch of a parallel circuit is open, current can still flow through the other branches.

Front

What is the effect of adding more resistors in parallel on the total resistance?

Back

Adding more resistors in parallel decreases the total resistance of the circuit.

Front

How do you calculate the voltage drop across a resistor in a parallel circuit?

Back

The voltage drop across a resistor in a parallel circuit is equal to the source voltage.

Front

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

Back

In a parallel circuit, the current is inversely proportional to the resistance; as resistance decreases, current increases.

Front

What is the significance of the open switch in a parallel circuit?

Back

An open switch in a parallel circuit prevents current from flowing through that branch, but does not affect the current in other branches.

Front

How do you determine the total current supplied by the battery in a parallel circuit?

Back

The total current supplied by the battery in a parallel circuit is the sum of the currents through each branch.
