A Wheatstone bridge consists of four resistors in parallel.

More Questions from Series-Parallel Circuits

• The higher the range setting, the less the internal resistance and the greater the load effect of the voltmeter on a circuit.
• A resistor ladder network is a special type of series-parallel circuit.
• A smaller-value load resistor will cause the output voltage to change more than a larger-value one.
• Using Kirchhoff's voltage law, you can find the voltages across certain parts of a series-parallel circuit.
• Using the current-divider formula, you can find the current in any branch of a series-parallel circuit.
• To derive 18 V and 12 V from a 24 V supply requires a voltage divider with three taps.
• A Wheatstone bridge is often shown in a "diamond" configuration.
