Physics: If v = 10v, what value of r would limit i to 10ma? (if you have 10 volts, what resistance would be needed to limit the current to 10 milliamps)

If v = 10v, what value of r would limit i to 10ma?

$1000 \Omega$

Explanation:

The relationship between voltage, resistance and current in a circuit is given by Ohm's law:

V=RI

where

V is the voltage

R is the resistance

I is the current

In this problem, we have:

V = 10 V

R = ?

I = 10 mA = 0.010 A

Therefore, we can re-arrange the equation to find R:

$R=\frac{V}{I}=\frac{10 V}{0.010 A}=1000\Omega$
