Front

What unit is used to measure current?

Back

Amps

Front

What is a circuit?

Back

A closed loop that allows for current to flow continuously.

Front

What unit is used to measure resistance?

Back

Ohms

Front

Which battery voltage will light up a bulb the brightest?

Back

12 V

Front

True or False: If the switch is open in a circuit, current will still flow.

Back

False

Front

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

Back

Ohm's Law states that V = I * R, where V is voltage, I is current, and R is resistance.

Front

What is the function of a resistor in a circuit?

Back

A resistor limits the flow of current in a circuit.

Front

What happens to current if resistance increases while voltage remains constant?

Back

The current decreases.

Front

What is the role of a battery in a circuit?

Back

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

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, while in a parallel circuit, components are connected across the same voltage source.
