With that said, here’s how to find ammo mod circuit boards in MW3 zombies ... playing games or catching up on his favourite TV series, he's writing about them.

You need to know how to measure the current that flows through a component in a circuit and the voltage across it. The ammeter must be connected in series with the component – remember ...

A LED takes a current of \(12.5 mA\) when the voltage across it is 2 V. Draw a suitable circuit and calculate the value of the series resistor needed to operate the LED from a \(9 V\) battery.
