Exam 7: Series-Parallel Circuits

If one 120 V, 100 W bulb was connected across a 240 V source,

Each branch current equals the voltage applied across the branch divided by the total resistance in the branch.

A high resolution ______________ can be used to determine the value of an unknown resistor.

What is a circuit that is used to determine the value of an unknown resistance?

A variety of sensors are used in bridge circuits for detecting changes in

When a parallel branch contains series resistors, both resistors

There can be more than two parallel resistances in a bank and

A variety of ______________ are used in bridge circuits for detecting changes in pressure, flow, light, etc.

When a parallel bank exists in a series path, both resistors have the same

Any circuit that combines both series and parallel connections is a

In a series circuit containing three or more components, the voltage across the defective component changes in a direction that is opposite to the direction of the change in voltage across good components.

A Wheatstone bridge is a circuit that is used to determine the value of an unknown ______________.

There can be more than two parallel resistances in a bank and any number of banks in series.

A variety of sensors are used in bridge circuits for detecting changes in pressure, flow, light, and temperature.

What type circuit is used when it is necessary to obtain different voltage and current values from a single supply voltage?

The ratio arm can be varied in most cases, typically in multiples of

When a parallel bank exists in a series path, both resistors have the same current flowing through them.

One method used to accurately determine the value of an unknown resistor is by using a(n)

When the Wheatstone bridge is balanced, it can be analyzed simply as

A short within a series-parallel circuit means that the circuit will definitely draw excessive current from the voltage source.
