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 the formula to calculate voltage in a circuit?

Back

Voltage (V) can be calculated using Ohm's Law: V = I × R, where I is the current in Amps and R is the resistance in Ohms.

Front

What is the unit of electrical resistance?

Back

The unit of electrical resistance is the Ohm (Ω).

Front

What type of current is produced by a battery?

Back

A battery produces direct current (DC), which flows in one direction.

Front

What is a conductor?

Back

A conductor is a material that allows the flow of electric current, typically metals like copper and gold.

Front

What is an insulator?

Back

An insulator is a material that resists the flow of electric current, such as rubber or glass.

Front

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

Back

The relationship is defined by Ohm's Law: V = I × R.

Front

What is the difference between AC and DC?

Back

AC (alternating current) changes direction periodically, while DC (direct current) flows in one direction.

Front

What is the function of a resistor in a circuit?

Back

A resistor limits the flow of electric current in a circuit.

Front

What is the role of a battery in an electrical circuit?

Back

A battery provides the voltage needed to push current through the circuit.
