Electricity

Front

What is the relationship between voltage, current, and resistance in an electric circuit?

Back

Ohm's Law states that Voltage (V) = Current (I) × Resistance (R).

Front

What is the unit of electric current?

Back

The unit of electric current is the Ampere (A).

Front

What is the unit of resistance?

Back

The unit of resistance is the Ohm (Ω).

Front

What device is used to measure voltage in an electric circuit?

Back

A voltmeter is used to measure voltage.

Front

What happens to the current in a circuit if the resistance increases while the voltage remains constant?

Back

The current decreases.

Front

In a series circuit, how does the total voltage relate to the individual voltages across each component?

Back

The total voltage is the sum of the individual voltages across each component.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where the components are connected across common points, providing multiple paths for current.

Front

What is the effect of adding more resistors in series to a circuit?

Back

Adding more resistors in series increases the total resistance.

Front

What is the effect of adding more resistors in parallel to a circuit?

Back

Adding more resistors in parallel decreases the total resistance.

Front

What is the function of an ammeter in a circuit?

Back

An ammeter measures the current flowing through a circuit.
