Series and Parallel Circuits

Front

What is a series circuit?

Back

A circuit in which the components are connected end-to-end, so that the current flows through each component in turn.

Front

What is a parallel circuit?

Back

A circuit in which the components are connected across common points or junctions, providing multiple paths for the current.

What is total resistance in a series circuit?

Back

The sum of the individual resistances: RT = R1 + R2 + R3 + ...

Front

What is total resistance in a parallel circuit?

Back

The reciprocal of the sum of the reciprocals of the individual resistances: 1/RT = 1/R1 + 1/R2 + 1/R3 + ...

Front

What is Ohm's Law?

Back

The relationship between voltage (V), current (I), and resistance (R) in a circuit: V = I × R.

Front

What does the resistance of a wire indicate?

Back

How tough it is for electrons to flow through it.

Front

What is an insulator?

Back

A material in which electrons are not able to move easily, preventing the flow of electric current.

Front

What is a conductor?

Back

A material that allows electrons to flow easily, facilitating the conduction of electricity.

Front

How do you calculate current in a circuit?

Back

Current (I) can be calculated using Ohm's Law: I = V / R.

Front

What is the unit of resistance?

Back

Ohm (Ω).
