What is a series circuit?

Back

A series circuit is a type of electrical circuit in which components are connected end-to-end, so that the current flows through each component in turn. If one component fails, the entire circuit is broken.

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit in which components are connected across common points or junctions, providing multiple paths for the current. If one component fails, the current can still flow through other paths.

What happens in a series circuit when one bulb goes out?

Back

In a series circuit, if one bulb goes out, the entire circuit stops working because the current cannot flow through the broken path.

Front

What happens in a parallel circuit when one bulb goes out?

Back

In a parallel circuit, if one bulb goes out, the other bulbs continue to work because there are multiple paths for the current to flow.

How do you calculate total resistance in a series circuit?

Back

In a series circuit, total resistance (R_total) is the sum of all individual resistances: R_total = R1 + R2 + R3 + ...

How do you calculate total resistance in a parallel circuit?

Back

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

What is the unit of resistance?

Back

The unit of resistance is Ohm (Ω).

What is a resistor?

Back

A resistor is a component in an electrical circuit that resists the flow of current, creating a voltage drop.

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to drive the current through the circuit.

What is an ammeter?

Back

An ammeter is a device used to measure the current flowing through a circuit.
