Quiz on Series and Parallel Circuits

What is a series circuit?

• A circuit that has no resistors

• A circuit that uses alternating current

• A circuit with only one path for current

• A circuit with multiple paths for current

In a series circuit, the current is:

• Different in each part

• The same in all parts

• Zero in all parts

• Only flows through the battery

What is the formula for total resistance in a series circuit?

• RT = V/I

• RT = R1 + R2 + R3

• RT = R1 * R2 * R3

• RT = 1/R1 + 1/R2 + 1/R3

What does VT represent in a series circuit?

• Voltage across a single resistor

• Total voltage

• Total current

• Total resistance

According to Ohm's law, the voltage across a resistor is calculated as:

• V = R/I

• V = I + R

• V = IR

• V = I/R

If R1 = 45Ω and R2 = 60Ω in a series circuit, what is the total resistance?

• 60Ω

• 45Ω

• 105Ω

• 15Ω

What is a parallel circuit?

• A circuit with multiple paths for current

• A circuit that only uses resistors

• A circuit that has no voltage source

• A circuit with only one path for current

In a parallel circuit, the voltage across each component is:

• Different for each component

• Only present in one component

• The same for all components

• Zero across all components

What is the formula for total current in a parallel circuit?

• IT = V/R

• IT = I1 * I2 * I3

• IT = I1 + I2 + I3

• IT = R/V

How is total resistance in a parallel circuit calculated?

• RT = V/IT

• RT = I/V

• RT = R1 + R2 + R3

• RT = 1/R1 + 1/R2 + 1/R3
