A voltage of 0.02 Volts across a shunt indicates which of the following currents?

To determine the current indicated by a voltage of 0.02 Volts across a shunt, it's essential to understand the relationship between voltage, current, and the resistance of the shunt. Shunt resistors are typically designed with a specific resistance value to provide a known voltage drop when a certain current flows through them.

In many common shunt applications, the relationship is defined by Ohm's Law, which states that the voltage (V) across the resistor is equal to the current (I) flowing through it multiplied by the resistance (R), or V = I × R.

In this case, if the shunt has been calibrated such that a voltage drop of 0.02 Volts corresponds to a specific current reading, you can infer that 0.02 Volts relates to a higher current value if the resistance is low.

Generally, shunts are designed to provide a small but measurable voltage drop that corresponds to larger current values. Often, for a common shunt that produces mV for higher currents, a voltage of 0.02 Volts can indicate a significant current, and it's common for this type of shunt to indicate around 4.0 Amperes for a voltage of 0.02
