Question

When a 10-V battery is connected to a resistor, 2 A of current flow in the resistor. What is the resistor's value

Answer 1

Hi there!

We can use Ohm's law to solve:

`V = IR`

V = Potential Difference (V)
I = Current (A)
R = Resistance (Ω)

We can rearrange the equation to solve for resistance:

`R = (V)/(I)`

Plug in the given values to solve.

`R = (10)/(2) = \boxed{5 \Omega}`
