If a current shunt is rated 15A/50mV and has a voltage drop of 28mV, what is the current flowing through the shunt?

If a current shunt is rated 15A/50mV and has a voltage drop of 28mV, what is the current flowing through the shunt?

• A. 8.0A
• B. 8.4A
• C. 6A
• D. 2.5A

Answer: (B)

To determine the current flowing through the shunt, we start by understanding the specifications of the shunt. The shunt is rated at 15A with a corresponding voltage drop of 50mV. This means that when a current of 15A flows through the shunt, it generates a voltage drop of 50mV across it. To find the current corresponding to a voltage drop of 28mV, we can use the proportional relationship established by the shunt's rating. First, we calculate the current per millivolt produced by the shunt: \[ \text{Current per mV} = \frac{15A}{50mV} = 0.3 A/mV \] Now, we can find the current that corresponds to a voltage drop of 28mV: \[ \text{Current} = \text{Voltage drop} \times \text{Current per mV} \] \[ \text{Current} = 28mV \times 0.3 A/mV = 8.4A \] Thus, the current flowing through the shunt when the voltage is 28mV is indeed 8.4A. This demonstrates how

To find the current corresponding to a voltage drop of 28mV, we can use the proportional relationship established by the shunt's rating. First, we calculate the current per millivolt produced by the shunt:

[

\text{Current per mV} = \frac{15A}{50mV} = 0.3 A/mV

]

Now, we can find the current that corresponds to a voltage drop of 28mV:

[

\text{Current} = \text{Voltage drop} \times \text{Current per mV}

]

[

\text{Current} = 28mV \times 0.3 A/mV = 8.4A

]

Thus, the current flowing through the shunt when the voltage is 28mV is indeed 8.4A. This demonstrates how
