Front

What is the total resistance in a circuit with a total resistance of 5.7 ohms?

Back

5.7 ohms

Front

When resistors are connected in parallel, is the combined resistance smaller or larger than the individual resistance?

Back

Smaller

Front

What is the total current flowing through a circuit if it is measured at 0.154 A?

Back

0.154 A

Front

What is the total resistance in a circuit with a total resistance of 4 ohms?

Back

4 ohms

Front

Which best describes a parallel circuit?

Back

Electricity flows along more than one pathway.

Front

Define resistance in an electrical circuit.

Back

Resistance is a measure of the opposition to the flow of electric current, measured in ohms.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R). Formula: V = I * R.

Front

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

Back

The total resistance decreases.

Front

What is the unit of measurement for electric current?

Back

Ampere (A).

Front

What is the formula to calculate total resistance (R_total) in a parallel circuit with two resistors (R1 and R2)?

Back

1/R_total = 1/R1 + 1/R2.
