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.

Front

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

Back

The total resistance decreases as more resistors are added in parallel.

Front

How is the voltage distributed 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 (R_total) in a parallel circuit?

Back

1/R_total = 1/R1 + 1/R2 + 1/R3 + ...

Front

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

Back

The other branches continue to operate normally, as they have their own separate paths for current.

Front

What is the current distribution in a parallel circuit?

Back

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

Front

What is the effect of adding more light bulbs in parallel on their brightness?

Back

Adding more light bulbs in parallel does not decrease their brightness, as each bulb receives the full voltage.

Front

In a parallel circuit, if one bulb burns out, what happens to the others?

Back

The other bulbs remain lit because they are on separate branches.

Front

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

Back

The voltage across each component is constant, while the current can vary depending on the resistance of each branch.

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit where components are connected end-to-end, so there is only one path for current to flow.
