Resistors in Parallel

What happens to the current when it reaches a branch with two resistors in parallel?

• It stops completely.

• It splits into two paths.

• It doubles in speed.

• It reverses direction.

How is the total current in a parallel circuit related to the currents in its branches?

• It is the average of the branch currents.

• It is less than the smallest branch current.

• It is equal to the sum of the branch currents.

• It is greater than the largest branch current.

What remains constant along an ideal wire in a parallel circuit?

• Current

• Power

• Voltage

• Resistance

According to Ohm's Law, how is current through a resistor calculated?

• Current equals voltage minus resistance.

• Current equals voltage divided by resistance.

• Current equals resistance times voltage.

• Current equals resistance divided by voltage.

What is the relationship between total resistance and individual resistances in a parallel circuit?

• Total resistance is the product of individual resistances.

• Total resistance is the sum of individual resistances.

• Total resistance is the sum of the reciprocals of individual resistances.

• Total resistance is the reciprocal of the sum of the reciprocals of individual resistances.

If a parallel circuit has resistors of 20 ohms and 5 ohms, what is the equivalent total resistance?

• 15 ohms

• 5 ohms

• 25 ohms

• 4 ohms

What is the total current in a circuit with a 16-volt battery and a total resistance of 4 ohms?

• 4 amps

• 8 amps

• 16 amps

• 12 amps

How is the current through a 20-ohm resistor calculated if the voltage across it is 16 volts?

• 4 amps

• 3.2 amps

• 1.2 amps

• 0.8 amps

What is the current through a 5-ohm resistor if the voltage across it is also 16 volts?

• 4 amps

• 2.5 amps

• 1.6 amps

• 3.2 amps

Why does more current flow through the resistor with less resistance in a parallel circuit?

• Because it has a higher voltage.

• Because it has a lower voltage.

• Because it generates more power.

• Because it allows easier flow of electrons.
