I thought that there was too much on that circuit so after I jumped the braker from 15 amp to 20 but still the lights dim

Changing a breaker to a higher amp rating is a fire hazard, change it back.

If the lights dimming is only one circuit, there is a losee connection in that circuit.

If the lights dim thruout the whole home, there is a loose connection anywhere from the utility connections through to your meter or panelboard.


Both require a qualified electrician to troubleshoot, locate and repair the fault.
