Resistance ® close resistance (R)How difficult it is for current to flow. increases when components, for example a lamp, are added to a circuit in series. Potential difference close potential ...

To measure the current flowing through a component in a circuit, you must connect the ammeter in series with it. Remember, electric current is measured in amperes, or amps for short.

For example, consider a case where you need to supply a higher voltage for a MOSFET gate that doesn’t draw much current ... This is Circuit VR because not only are we going to discuss the ...
