Electric Circuit Concepts and Calculations

Front

What is a conductor?

Back

A material that allows the flow of electric current, typically metals like copper and aluminum.

Front

What is an insulator?

Back

A material that does not allow electrons to move easily, preventing the flow of electric current, such as rubber or glass.

Front

What is resistance in an electric circuit?

Back

The opposition to the flow of electric current, measured in ohms (Ω).

Front

What is voltage?

Back

The electric potential difference between two points in a circuit, measured in volts (V).

Front

What is the formula for calculating voltage?

Back

Voltage (V) = Current (I) × Resistance (R).

Front

What is current?

Back

The flow of electric charge, measured in amperes (A).

Front

What is the relationship between voltage, current, and resistance?

Back

Ohm's Law states that V = I × R.

Front

What happens to current in a series circuit?

Back

The current remains the same throughout all components in a series circuit.

Front

What happens to voltage in a series circuit?

Back

The total voltage is divided among the components in a series circuit.

Front

What happens to current in a parallel circuit?

Back

The total current is divided among the parallel branches.
