Unit 6, 7

Question 2

When calculating the total values of a set of resistors in a series circuit:

Which values will remain identical across each resistor?

Answer 2

I (Current, Amps)

Question 3

How to find the wattage (P) given current and volts?

Answer 3

P = Volts x Current

Question 4

A circuit that has only one path for current flow. Because there is only one path for current flow, the current is the same at any point in the circuit. This describes what type of circuit?

Answer 4

Series circuit

Question 5

The individual voltage drops in a series circuit can be added to -

Answer 5

equal the applied voltage

Question 6

The individual resistor resistance value in a series circuit can be added to equal the -

Answer 6

total resistance of the circuit

Question 7

The total power in any circuit is equal to the sum of the power dissipated -

Answer 7

all parts of the circuit.

Question 8

Circuits that have more than one path for current flow is called -

Answer 8

A parallel circuit

Question 9

the voltage drop across any branch of a parallel circuit is the same as the -

Answer 9

applied voltage. . For this reason, most electric circuits in homes are connected in parallel. Each lamp and receptacle is supplied with equal volts.

Question 10

In terms of voltage drop at each individual resistor, what sets a parallel and series circuit apart?

Answer 10

At each resistor in a series circuit the voltage drop will not equal the applied voltage.

At each resistor in a parallel circuit, the voltage drop will equal the applied voltage.

Question 11

The total resistance of a parallel circuit is always less than the resistance of the -

Answer 11

lowest value resistor, or branch, in the circuit

Question 12

Calculating Series Circuit Values
Three rules can be used with Ohm’s law for finding values of voltage, current, resistance,
and power in any series circuit:

Answer 12

1. The current is the same at any point in the circuit.
2. The total resistance is the sum of the individual resistors.
3. The applied voltage is equal to the sum of the voltage drops across all the resistors.

Question 13

Summarize a series circuit:

Voltage drop at each resistor -

Total voltage -

Current value at each resistor -

Total current -

Total resistance -

Answer 13

Voltage drop is equal to the applied voltage, at each resistor.

Equal to the applied voltage

Proportional to the resistance

Sum of the current at each resistor

Less than the lowest value of resistor resistance
