Why does hitting a tv remote make it to work sometimes?

Today when I was watching tv , suddenly tv remote stopped working . I thought maybe the batteries of remote got exhausted . At that time , I accidentally hit the remote twice . After that , remote control started working !!!


This malfunctioning of tv remote is quite common . Everyone of us experienced it . The batteries we use in the remote control stays there for a long time . Because of this , an oxidation layer forms between the terminals and batteries of remote .


Now this oxidation layer is having a high resistivity to the flow of current . Thus it hampers the smooth working of remote .


At that time , if we hit the remote , it shakes the inside of remote . By hitting , we are slightly repositioning the battery contacts . Also it shocks the terminals of remote , thereby forming a scratch in the oxidation layer .


It reduces the resistance offered by the oxidation layer and allows the current to flow through it again . And we feel that remote control has started working again !!!
