Question

How much voltage is required to run 0.054 A of current through a 15 2

resistor? Use AV = IR.

O A. 0.81 V

O B. 1.2 V

O c. 2.8x10²v

O D. 3.6 x 10-3 v

Answer 1

The correct option is (a).

Step-by-step explanation:

Given that,

Current flowing through the resistor, R = 0.054 A

Resistance of the resistor, R = 15 ohms

We need to find the voltage. We know that, Ohm's law gives the relation between voltage, current and resistance i.e.

V = IR

Put all the values,

`V=0.054 * 15\\\\V=0.81\ V`

So, the required voltage is equal to 0.81 volts.
