Maximum current problem. If the current on your power supply exceeds 500 mA it can damage the supply. Suppose the supply is set for 37 V. What is the smallest resistance you can measure?

Respuesta :

Answer:

Smallest resistance will be 74 ohm

Explanation:

We have given that if current is exceeds from 500 mA then it can damage the supply, so current i = 500 mA = 0.5 A

Supply is connected to a voltage source of 37 colt

So V = 37 volt

We have to find the smallest resistance

According to ohm's law resistance will be the ratio of voltage and current and here we have given maximum current which will given smallest resistance

So resistance [tex]R=\frac{V}{i}=\frac{37}{0.5}=74ohm[/tex]

So smallest resistance will be 74 ohm

The smallest resistance you can measure is equal to 74 Ohms.

Given the following data:

  • Current = 500 mA
  • Voltage = 37 Volts.

To calculate the smallest resistance you can measure, we would apply Ohm's law:

The formula for Ohm's law.

Mathematically, Ohm's law is given by this formula;

[tex]V=IR[/tex]

Where;

  • V is the voltage measured in Volts.
  • I is the current measured in Ampere.
  • R is the resistance measured in Ohms.

Making R the subject of formula, we have:

[tex]R=\frac{V}{I}[/tex]

Substituting the given parameters into the formula, we have;

[tex]R=\frac{37}{500 \times 10^{-3}}[/tex]

Resistance, R = 74 Ohms.
