Understanding Combination Circuits

What is a series connection in an electric circuit?

• Devices are connected with a switch.

• Devices are connected in separate branches.

• Devices are connected back to back.

• Devices are connected in a loop.

How do you calculate the equivalent resistance for resistors in series?

• Multiply the resistance values.

• Add the resistance values.

• Divide the resistance values.

• Subtract the resistance values.

What is the formula for calculating equivalent resistance in parallel circuits?

• Sum the resistance values.

• Multiply the resistance values.

• Sum the reciprocals of the resistance values and take the reciprocal of the result.

• Subtract the resistance values.

In a combination circuit, what is the first step in finding the equivalent resistance?

• Calculate the total voltage.

• Reduce groups of resistors to a single resistor.

• Find the current in the circuit.

• Identify the power source.

What happens to electric potential as charge passes through a resistor?

• It increases.

• It decreases.

• It fluctuates.

• It remains constant.

How is the current in the battery related to the current in resistors outside the branches in a combination circuit?

• It is always greater.

• It is unrelated.

• It is equal.

• It is always less.

If two branch resistors have the same resistance, how does the current divide?

• Equally between the branches.

• Unequally based on voltage.

• It does not divide.

• All current goes through one branch.

What is the equivalent resistance of two 16 ohm resistors in parallel?

• 8 ohms

• 16 ohms

• 32 ohms

• 4 ohms

How do you calculate the current in a resistor if you know the voltage drop and resistance?

• Subtract resistance from voltage drop.

• Add voltage drop and resistance.

• Divide voltage drop by resistance.

• Multiply voltage drop by resistance.

In a circuit with different branch resistors, how is the total voltage drop related to the battery voltage?

• It is always less.

• It is unrelated.

• It is equal to the battery voltage.

• It is always more.
