Voltage in Parallel Circuit Quiz

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

• The voltage across each branch in a parallel circuit is alternating.

• The voltage across each branch in a parallel circuit is zero.

• The voltage across each branch in a parallel circuit is different.

• The voltage across each branch in a parallel circuit is the same.

If two resistors are connected in parallel, how does the total voltage compare to the voltage across each resistor?

• The total voltage is unrelated to the voltage across each resistor.

• The total voltage is lower than the voltage across each resistor.

• The total voltage is higher than the voltage across each resistor.

• The total voltage is the same as the voltage across each resistor.

In a parallel circuit, how is the total current related to the individual branch currents?

• The total current is less than the sum of the individual branch currents

• The total current is unrelated to the individual branch currents

• The total current is equal to the sum of the individual branch currents.

• The total current is greater than the sum of the individual branch currents

What happens to the total resistance in a parallel circuit as more branches are added?

• The total resistance decreases.

• The total resistance increases.

• The total resistance stays the same.

• The total resistance becomes infinite.

If one branch in a parallel circuit has a higher resistance than the others, what can be said about the current in that branch?

• The current in that branch will be higher than the others.

• The current in that branch will be the same as the others.

• The current in that branch will be lower than the others.

• The current in that branch will be zero.

What is the formula to calculate the total resistance in a parallel circuit?

• Rt = R1 - R2 - R3 - ...

• Rt = R1 + R2 + R3 + ...

• Rt = R1 * R2 * R3 * ...

• 1/Rt = 1/R1 + 1/R2 + 1/R3 + ...

What is the effect of adding more branches to a parallel circuit on the total current?

• The total current increases.

• The total current remains the same.

• The total current decreases.

• The total current becomes zero.

How does the total current in a parallel circuit compare to the individual branch currents?
