Exploring Series and Parallel Circuit Concepts

What does the epsilon symbol next to a battery represent?

• Electromotive force

• Charge of the battery

• Terminal voltage

• Total resistance

What happens to the current when two resistors are in series?

• The current becomes zero.

• The current doubles.

• The current is halved.

• The current through each resistor is the same.

How does the equivalent resistance change when resistors are added in series?

• It becomes zero.

• It increases.

• It remains constant.

• It decreases.

In a parallel circuit, how do the electric potential differences across each resistor compare?

• They are the same.

• They are zero.

• They are different.

• They are undefined.

What is the equivalent resistance of resistors in parallel?

• Inverse of the sum of the inverses of the resistances

• Product of the resistances

• Sum of the resistances

• Average of the resistances

How does adding capacitors in parallel affect the equivalent capacitance?

• It becomes zero.

• It decreases.

• It remains the same.

• It increases.

What effect does the internal resistance of a battery have on terminal voltage?

• Increases it

• Doubles it

• Decreases it

• No effect

What is the correct statement about charges in a series capacitor setup?

• Charges on all plates are the same.

• Charges are only on the outer plates.

• Charges on all plates are different.

• No charges exist on the plates.

What is the role of an ammeter in a circuit?

• To measure resistance

• To measure charge

• To measure voltage

• To measure current

Where should a voltmeter be placed in a circuit?

• In series with the circuit element

• It does not need to be connected

• In parallel with the circuit element

• Directly on the battery
