What does the use of a shunt in a measurement circuit help to determine?

• A. Resistance values
• B. Voltage drops
• C. Current values
• D. Power consumption

Answer: (C)

The use of a shunt in a measurement circuit primarily helps to determine current values. A shunt resistor, which has a known low resistance, is placed in parallel with the measuring device. When current flows through the circuit, a small voltage drop occurs across the shunt due to Ohm's Law (Voltage = Current x Resistance). By accurately measuring this voltage drop and knowing the resistance of the shunt, one can calculate the current flowing through the circuit. This method is particularly useful in scenarios where direct measurement of high currents would be impractical or unsafe. The primary function of a shunt is to convert a current level into a measurable voltage, which can then be analyzed for various applications. When set up correctly, this technique provides a safe and effective way to monitor current levels without directly interrupting the circuit. While resistance values, voltage drops, and power consumption can be measured within a circuit, they depend on different setups and measuring principles rather than the specific use of a shunt for current measurement.
