A voltage of 40 volts is causing a current to move through a material with 4 ohms of resistance. What is the current?

A. 160 volts
B. 160 amps
C. 10 volts
D. 10 amps
E. 4 volts
F. 4 amps

Answer :

We start with Ohm's Law, which states that the current [tex]$I$[/tex] is given by

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

where [tex]$V$[/tex] is the voltage (in volts) and [tex]$R$[/tex] is the resistance (in ohms).

Given that the voltage is [tex]$40$[/tex] volts and the resistance is [tex]$4$[/tex] ohms, we substitute these values into the formula:

[tex]$$
I = \frac{40}{4}
$$[/tex]

Simplifying the fraction, we find:

[tex]$$
I = 10 \text{ amps}
$$[/tex]

Thus, the current is [tex]$\boxed{10 \text{ amps}}$[/tex].
