Electrical resistance

Front

What happens to the total resistance when more resistors are added in series?

Back

The total resistance goes up.

Front

What is the voltage across each bulb in a parallel circuit?

Back

The voltage will be the same across each bulb.

Front

Which resistor allows the least current flow: 1 ohm, 100 ohms, 1000 ohms, or 0.5k ohms?

Back

1000 ohms prevents the most current flow.

Front

What effect do electrons flowing through a resistor have on it?

Back

Electrons heat up the resistor.

Front

In a series circuit, how does the current passing through bulbs compare?

Back

The current passing through bulbs in series will be the same.

Front

What is electrical resistance?

Back

Electrical resistance is a measure of the opposition to the flow of electric current.

Front

What unit is electrical resistance measured in?

Back

Ohms (Ω) is the unit of electrical resistance.

Front

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

Back

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

Front

What happens to the total resistance in a parallel circuit when more resistors are added?

Back

The total resistance goes down.

Front

What is a resistor?

Back

A resistor is a component that resists the flow of electric current.
