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

The current flowing through the resistor is 2.44 x 10^-3 A.

Step-by-step explanation:

To find the current flowing through the resistor, you can use Ohm's Law which states that the current (I) is equal to the potential difference (V) across the resistor divided by the resistance (R). In this case, the potential difference across the resistor is 4.4 × 10 V and the resistance is 1.8 kΩ (which can be converted to 1.8 x 10^3 Ω). Using Ohm's Law:

I = V / R = (4.4 x 10) / (1.8 x 10^3) = 2.44 x 10^-3 A

Therefore, the current flowing through the resistor is 2.44 x 10^-3 A.

Answer 2

0.024 A

Step-by-step 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=(V)/(R)=(44 V)/(1800 \Omega)=0.024 A`
