Circuits and Ohms Law 5th

Front

What is a series circuit?

Back

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

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical circuit through which current can flow without interruption.

Front

What is an open circuit?

Back

An open circuit is a broken circuit where the current cannot flow due to a break or disconnection.

Front

What is the symbol for a battery in a circuit diagram?

Back

The symbol for a battery is two parallel lines, with the longer line representing the positive terminal and the shorter line representing the negative terminal.

Front

What happens to the current in a series circuit if one component fails?

Back

If one component in a series circuit fails, the entire circuit is broken and the current stops flowing.

Front

What happens to the current in a parallel circuit if one component fails?

Back

If one component in a parallel circuit fails, the current can still flow through the other components, so the circuit remains operational.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. It is expressed as V = I × R.

Front

What is the unit of resistance?

Back

The unit of resistance is the ohm, symbolized by the Greek letter omega (Ω).

Front

What is the unit of current?

Back

The unit of current is the ampere, often shortened to amp, symbolized by 'A'.
