Question

The potential difference across a resistor is 4.4 × 10 V. If the resistance of the resistor is 1.8 k?, how much current flows through the resistor?

Answer 1

Answer:

0.024 A

Explanation:

We can solve the problem by using Ohm's law, which states that:

$V=RI$

where

V is the potential difference across a resistor

R is the resistance of the resistor

I is the current flowing through it

In this problem, we have:

$V=4.4\cdot 10 V = 44 V$

$R=1.8 k \Omega=1800 \Omega$

Therefore, we can re-arrange the equation to calculate I, the current:

$I=\frac{V}{R}=\frac{44 V}{1800 \Omega}=0.024 A$
