Question

What must be the current in a resistor if the drop in potential across it is 0.750V and it uses 2.00W of power?1.25A1.50A0.375A2.67A

Answer 1

Given data:

The voltage drop across the resistor is V=0.750 V.

The power used by resistor is P=2.00 W.

The expression for the power in terms of voltage and current,

`P=VI`

Substitute the given values in above equation,

`\begin{gathered} 2=(0.75)I \\ I=2.67\text{ A} \end{gathered}`

Thus, the current in the resistor is 2.67 A.

Final Answer: 2.67 A.
